TDA8787AHL/C3,151

Data Acquisition - ADCs/DACs - Special Purpose

TDA8787AHL/C3,151 is a special purpose integrated circuit (IC) for data acquisition, manufactured by NXP Semiconductor.

Application Field

The TDA8787AHL/C3,151 is used for medium-to-high speed data acquisition and signal processing. The device is well-suited for applications such as digital audio and video processing, digital film processing, control and automation, industrial, governmental, and aerospace systems.

Working Principle

The TDA8787AHL/C3,151 integrates a high throughput, low noise A/D converter and a programmable gain amplifier (PGA) into a single IC. The device allows for input signal sampling with 16-bit resolution and sampling rates up to 100Msps. The PGA has two wide-range gain settings for increased dynamic range for signal conditioning and can be programmed for different gain configurations. The device also features a 4-bit programmable filter for further noise filtering.

The TDA8787AHL/C3,151 uses an advanced offset cancellation technique to optimize linearity and accuracy. A built-in digital signal processor, known as the Digital Baseband Processor (DBP), is used to manage digital filtering, data packing, and other signal conditioning. This feature is programmable to provide enhancement to the acquired signal.

The TDA8787AHL/C3,151 is equipped with an onboard low-power sleep mode and power management functions. This allows for configuration of the device’s power draw and provides improved power efficiency for portable systems.

Conclusion

The TDA8787AHL/C3,151 is an ideal device for high-speed data acquisition and signal processing. The device includes a low-noise A/D converter with high resolution, a programmable gain amplifier for increased dynamic range and signal conditioning, and a digital signal processor for data manipulation and filtering. With power management features and adjustable sleep mode, the TDA8787AHL/C3,151 is an excellent choice for applications demanding high performance data processing.
