Texas Instruments (TI) today announced a TPA2013D1, a monolithic filterless Class D audio power amplifier with integrated boost converter that provides constant output power for a variety of portable applications, such as personal navigation devices, PDAs. , mobile phones, portable media players, and handheld game consoles. With a combined 2.7W Class D amplifier and integrated boost converter, the overall efficiency is 85%, and the user's heat loss when playing music or making phone calls is small, helping to extend battery life.

The TPA2013D1 generates higher output power with lower supply voltage without distortion of the audio and can power a variety of external devices such as TI's TPA2010D1 and other similar Class D amplifiers. The device supports a wide operating voltage range of 1.8 V to 5.5 V, which simplifies power supply design and allows direct connection to the battery. The new device delivers 2.7W of maximum output power over a full 4 ohm load, while delivering 2.2 W of maximum output power in an 8 ohm load, plus the entire Li-Ion battery operating voltage from 2.3 V to 4.8 V. Adjustable constant output power up to 1.5W is available in the range. This feature allows the audio output power to be unaffected by battery voltage fluctuations, thereby maintaining sound quality and volume during battery discharge.

The TPA2013D1's innovative design eliminates the need for external components, so the total solution size including amplifiers, boost converters and external components is only 6.5 mm x 6.5 mm, which is more than 50% smaller than typical solutions. . Due to the reduced volume, outstanding features, high performance, and the combination of multiple advantages, it helps to reduce the overall system cost and design a more stylish and more distinctive end product.

Some key features of the TPA2013D1 help improve system audio quality. For example, all internal modules use the same reference clock, which suppresses audible beat noise that can be caused by the use of separate discrete and boost converters. The synchronous clock and very high power supply rejection ratio (PSRR) (95 dB at 217 Hz) help to further reduce noise in the system and avoid noise on the amplifier output, which is often the case with RF power amplifiers for GSM phones. .

The TPA2013D1 offers thermal and short-circuit protection with automatic recovery options to ensure excellent reliability and stable operation. The device's pinouts are carefully optimized to reduce EMI and meet the Federal Communications Commission's (FCC) EMI requirements.

The TPA2013D1 amplifier works with TI's broad portfolio of audio products, including portable audio converters such as the TLV320AIC3106, the TLV320DAC32 digital-to-analog converter, and the AureusTM platform for audio DSPs. TI provides hardware, software, system expertise and support for the entire audio signal chain to help customers accelerate time-to-market.

The TPA2013D1 Class D audio power amplifier is available now and is available from TI and its authorized distributors in a 2.3 mm x 2.3 mm 16-ball WCSP or 4 mm x 4 mm 20-pin QFN package. Samples and EVM are available on the TI website.

Industrial Router

What is an industrial router? Which industries are they mainly used in?

With the continuous development of the network and the continuous progress of various industries, some new concepts and development directions have actually emerged during the period. For example, from the current point of view, many enterprises in the development process in order to have good efficiency and speed, as well as the use of more functions, gradually began to use industrial routers. Of course, for this type of router, we also have a lot of problems, so today we will discuss to see, what is an industrial router? Which industries are they mainly used in?

What is an industrial router?
From the basic concept, an industrial router is a wireless data transmission function that provides users with wireless data transmission through a public wireless network. For example, we use mobile phone data to transfer things to another mobile phone or computer, in fact, the principle is very simple. Of course, the specific usage operation is different. In the process of use, the industrial router has the advantage of allowing multiple users to use the same integrated network system to access the network, which is also very convenient in the work. In fact, at present, industrial routers are gradually widely used in different industries, and the practicability is also very strong.

Industrial routers are mainly used in what industries?
The first is some of the contents summarized for the concept and basic principles of industrial routers, and for the use of industrial routers, it is also some of the issues that we are concerned about. From the current point of view, the first is widely used in intelligent transportation, such as in the application of high-definition electronic bayonet, road wireless video surveillance, vehicle monitoring or security monitoring, etc., which is also very important; Secondly, it is also widely used in the financial industry, such as the use of wireless atm self-service terminals, wireless pos machines or other applications; In addition, it is the application of the power industry, such as transformer remote monitoring management, circuit line video surveillance and substation video surveillance and so on. In short, the use of industrial routers is also more extensive.

How to choose an industrial router?
Although the industrial router is widely used now, the choice we made at the beginning is still more tangled, from the feedback of the market, Movingcomm router is actually very good. According to the needs of the industry environment, based on SD-WAN+ Internet of Things, intelligent networking can then be formed into a large local area network through the cloud platform router in many places. Therefore, the focus of security monitoring can also be concentrated to complete the work of remote video surveillance, but also to meet the needs of remote working, for some of the industries we mentioned earlier, the practicality of this program is also very good. Moreover, the technology of remote networking and intelligent networking is also very mature, and the security and stability are also good. In short, the advantages of Movingcomm router are still many.
