ADS7811
16-Bit 250kHz Sampling CMOS
ANALOG-to-DIGITAL CONVERTER
DESCRIPTION
The ADS7811 is a complete 16-bit sampling analog-
to-digital (A/D) converter featuring excellent AC
performance and a 250kHz throughput rate. The de-
sign 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.
