PRODUCT DESCRIPTION
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 interfaces to either +5 V or +3.3 V logic. Digital output pins can be placed in a high impedance state; the format of the output is straight binary coding. The AD876’s speed, resolution and single-supply operation ideally suit a variety of applicati...
