ADS8685IPW Description

Short technical summary and product information.

The ADS8685IPW is a 16-bit, successive approximation register (SAR) analog-to-digital converter (ADC) from Texas Instruments. It achieves a sampling rate of 500 kSPS and features a single-ended input with programmable bipolar voltage ranges up to ±12.288 V. The device integrates a programmable gain amplifier (PGA), an internal oscillator, and input over-voltage protection up to ±20 V.

 

Key specifications include a typical signal-to-noise ratio (SNR) of 92 dB, low power consumption of 29 mW, and support for both external and internal reference modes. The ADC operates from an analog supply of 4.75 V to 5.25 V and a digital I/O supply of 1.65 V to 5.25 V, making it suitable for systems with mixed voltage domains.

 

The ADS8685IPW is housed in a 16-pin TSSOP package (0.173" width, 4.40 mm) and supports surface-mount assembly. It is rated for extended industrial temperature range from -40°C to 125°C. The device uses an Enhanced SPI interface compatible with daisy-chain configurations.
