ADS8691IPWR Description

Short technical summary and product information.

The ADS8691IPWR is an 18-bit, successive approximation register (SAR) analog-to-digital converter (ADC) from Texas Instruments. It offers a sampling rate of 1 MSPS and includes an integrated analog front-end with programmable gain amplifier (PGA) and over-voltage protection.

 

Key specifications: It supports software-programmable bipolar input ranges (±12.288 V, ±10.24 V, ±6.144 V, ±5.12 V, ±2.56 V) and unipolar ranges (0 V to 12.288 V, etc.). The device achieves a typical SNR of 92.5 dB and operates from a 5V analog supply with a 1.65V to 5V digital I/O supply. Power consumption is typically 42 mW.

 

Design features: The ADC includes an on-chip 4.096V reference, an oscillator, and a multiSPI interface with daisy-chain capability. It provides constant resistive input impedance ≥1 MΩ and input overvoltage protection up to ±20 V. The operating temperature range is -40°C to +125°C.

 

Packaging: The device is available in a 16-TSSOP (0.173", 4.40mm Width) surface-mount package (supplier device package 16-TSSOP). It is listed as RoHS3 Compliant (unverified) and has an MSL of 1 (unlimited).
