AD875

The AD875 is a CMOS, low power 10-bit, 15 MHz analog-todigital converter (ADC). The AD875 combines high speed 10-bit resolution and performance with low power and single supply operation. By implementing a multistage pipelined architecture with output error correction logic, the AD875 offers accurate performance and guarantees no missing codes over the full operating temperature range. To minimize external voltage drops, the reference ladder top and bottom are provided with force and sense pins.

The AD875's digital I/Os can interface to either +5 V or +3.3 V logic. The AD875 can be placed into a standby mode of operation reducing the power below 50 mW. Digital output data can be placed in a high impedance state and is offered in a variety of formats, including straight binary and twos complement output.The AD875 also provides both underrange and overrange output bits, indicating when the analog input has exceeded the analog input range.

The AD875's speed, resolution and single-supply operation are ideally suited for a variety of applications in imaging, high speed data acquisition and communications. The AD875's low power and single supply operation are required for high speed portable applications. Its speed and resolution are ideally suited for charge coupled device (CCD) input systems such as color scanners, digital copiers, electronic still cameras and camcorders.

The AD875 is packaged in a space saving 48-pin thin quad flatpack (TQFP) and is specified over the commercial (0°C to +70°C) temperature range.
