The Texas Instruments ADS8688AIDBTR is a high-performance, 16-bit, 500 kSPS (kilo-samples per second) analog-to-digital converter (ADC) designed for precision data acquisition systems. It features an integrated analog front-end with overvoltage protection up to ±20 V and supports both bipolar and unipolar input ranges. The device is housed in a 38-pin TSSOP package and operates over an industrial temperature range of -40°C to +125°C.
16 Bit Analog to Digital Converter ADS8688AIDBTR Features
The ADS8688AIDBTR offers several key features that make it suitable for demanding applications. It integrates an 8-channel multiplexer with both automatic and manual scanning modes, allowing flexible input channel management. The device supports multiple programmable input ranges, including ±10.24 V, ±5.12 V, ±2.56 V, and 0 V to 10.24 V, ensuring high precision for various signal levels. Additionally, it includes a low-drift, on-chip 4.096-V reference voltage and a constant 1 MΩ input impedance, which simplifies circuit design and enhances stability. The ADC achieves excellent performance metrics, such as a signal-to-noise ratio (SNR) of 92 dB and total harmonic distortion (THD) of -102 dB, while maintaining low power consumption at 65 mW.
ADS8688AIDBTR Applications
