16-Bit 250kHz Sampling CMOS Analog-to-Digital Converter 28-SOIC -25 to 85
16-Bit 250kHz Sampling CMOS
ANALOG-to-DIGIT AL CONVERTER
DESCRIPTIONThe 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 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.
