ADS8684IDBT Description

Short technical summary and product information.

The Texas Instruments ADS8684IDBT is a high-performance 16-bit Analog-to-Digital Converter (ADC) with a successive approximation register (SAR) architecture. It offers an aggregate throughput of 500 kSPS across its 4 multiplexed input channels. The device supports channel-independent programmable input ranges, including bipolar options of ±10.24V, ±5.12V, and ±2.56V, as well as unipolar options of 10.24V and 5.12V.

 

Designed for industrial applications, the ADS8684IDBT operates with a 5V analog supply and a flexible 1.65V to 5.25V I/O supply. It boasts excellent performance characteristics, including a Signal-to-Noise Ratio (SNR) of 92 dB and a Total Harmonic Distortion (THD) of -102 dB. The ADC features an on-chip 4.096V reference with low drift, constant resistive input impedance of 1 MΩ, and input overvoltage protection up to ±20V.

 

This ADC is available in a 38-TSSOP package, suitable for surface mount applications. Its SPI-compatible interface supports daisy-chaining for expanded channel counts. The operating temperature range is -40°C to 125°C, making it ideal for demanding environments. Key features include a Programmable Gain Amplifier (PGA), an oscillator, and over-voltage protection.
