Introduction

TLV990-40PFBG4 is an Analog Front End (AFE) designed for general purpose data acquisition applications. It has an 8-bit resolution, built-in 16-channel multiplexer, and programmable gain amplifier. It is especially suitable for low-power, small-scale applications.

Features

The TLV990-40PFBG4 provides an 8-bit resolution and an integrated 16-channel multiplexer. It can be used to multiplex signals from multiple analog sources. The low-voltage differential signal (LVDS) output format allows for high-speed transmission of the multiplexed signals. The integrated programmable gain amplifier (PGA) provides a gain adjustment range of 0 to 9. The TLV990-40PFBG4 also features a low-power, low-noise architecture which makes it ideal for small-scale applications.

Application Field and Working Principle

TLV990-40PFBG4 is most commonly used in data acquisition applications, such as in medical instrumentation, automotive, industrial and consumer electronics. For example, it can be used in medical instruments such as ultrasound machines and ECGs. The integrated multiplexer allows the TLV990-40PFBG4 to multiplex signals from multiple analog sources and the integrated PGA allows for gain adjustment. This makes the TLV990-40PFBG4 ideally suited for low-power, small-scale applications.The TLV990-40PFBG4 operates at a voltage range of 5V to 30V and a power supply current of 13mA. It is composed of an 8-bit resolution ADC, a 16-channel multiplexer and a programmable gain amplifier.The input signal is first filtered by an anti-aliasing filter to reduce the noise before being fed into the ADC. After the ADC, the signal is multiplexed using the integrated 16-channel multiplexer. The multiplexed signal is then amplified and converted to LVDS format for faster data transmission. The gain of the signal can be adjusted by the integrated PGA.The TLV990-40PFBG4 also features built-in power management features such as power down, sleep mode, and low power mode. It also has a shutdown mode that can be used to reduce the power consumption of the device.

Conclusion

The TLV990-40PFBG4 is an integrated Analog Front End (AFE) for general purpose data acquisition applications. It features an 8-bit resolution, a 16-channel multiplexer, and a programmable gain amplifier. The low-power, low-noise architecture of the TLV990-40PFBG4 makes it ideal for small-scale applications. The integrated power management features make it suitable for portable and low-power applications.
