AD876
FUNCTIONAL BLOCK DIAGRAM
AVDD CLK SHA SHA GAIN The AD876 is a CMOS, 160 mW, 10-bit, 20 MSPS analog-todigital converter (ADC). The AD876 has an on-chip input
sample-and-hold amplifier. By implementing a multistage pipelined architecture with output error correction logic, the AD876
offers accurate performance and guarantees no missing codes
over the full operating temperature range. Force and sense connections to the reference inputs minimize external voltage drops.
The AD876 can be placed into a standby mode of operation
reducing the power below 50 mW. The AD876’s digital I/O …
