DescriptionThe AD876 is a CMOS, 160 mW, 10-bit, 20 MSPS analog-to- digital converter (ADC). The AD876 has an on-chip input sample-and-hold amplifier. By implementing a multistage pipe- lined 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 con-nections to the reference inputs m inimize 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 out- put is straight binary coding.
The AD876's speed, resolution and single-supply operation ideally suit a variety of applications in video, multimedia, imag- ing, high speed data acquisition and communications.
TheAD876's low power and single-supply operation satisfy require-ments for high speed portable applications. Its speed and reso-lution ideally suit charge coupled device (CCD) input systemssuch as color scanners, digital copiers, electronic still camerasand camcorders.
