Not Recommended for New Designs (NRND)

Replaced By ADS8505 – The device has the SAME FUNCTIONALITY as the compared device, but is not pin-for-pin equivalent and may not be parametrically equivalent. Lower power and available in SOIC and SSOP package
ADS8515 – The device has the SAME FUNCTIONALITY as the compared device, but is not pin-for-pin equivalent and may not be parametrically equivalent. Lower power version with improved performance and low voltage digital interface capability. Available in SOIC and SSOP package.

TI does not recommend using this part in a new design. This product continues to be in production to support existing customers.

Description

The ADS7811 is a complete 16-bit sampling analog-todigital (A/D) converter featuring excellent AC performance and a 250kHz throughput rate. The design includes a 16-bit capacitor-based SAR A/D converter with an inherent sample and hold (S/H), a precision reference, and an internal clock. Spurious-free dynamic range with a 100kHz full-scale sinewave input is typically greater than 100dB. The ±2.5V input range allows development of precision systems using only ±5V supplies. The converter is available in a 28-lead SOIC package specified for operation over the industrial -25°C to +85°C temperature range.
