16-Bit 250kHz Sampling CMOS
ANALOG-to-DIGITAL CONVERTER
DESCRIPTION
The ADS7815 is a complete 16-bit sampling analog-to-
digital (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 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.
