ADS7811

SBAS041A – NOVEMBER 1997 – REVISED NOVEMBER 2006

16-Bit 250kHz Sampling CMOS

ANALOG-to-DIGITAL CONVERTER

FEATURES

DESCRIPTION

● 250kHz SAMPLING RATE

● COMPLETE WITH S/H, REF, CLOCK, ETC.

● 96dB min SFDR WITH 100kHz INPUT

● 84dB min SINAD

The ADS7811 is a complete 16-bit sampling analog-to-

digital (A/D) converter featuring excellent AC

performance and a 250kHz throughput rate. The design

includes

16-bit capacitor-based SAR A/D

converter with an inherent sample and hold (S/H), a preci-

sion 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 develop-

ment 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 tempera-

ture range.

● ±2.5V INPUT RANGE

● 28-LEAD SOIC
