Analog Devices Inc. AD876JR

Single Channel Single ADC Pipelined 20Msps 10-bit Parallel 28-Pin SOIC W Tube
16-BIT DELTA-SIGMA ADC, SERIAL
The 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 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 stand-by 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 applications in video, multimedia, imaging, high speed data acquisition and communications. The AD876's low power and single-supply operation satisfy requirements for high speed portable applications. Its speed and resolution ideally suit charge coupled device (CCD) input systems such as color scanners, digital copiers, electronic still cameras and camcorders. The AD876 comes in a space saving 28-pin SOIC and 48-pin thin quad flatpack (TQFP) and is specified over the commercial (0°C to 70°C) temperature range. PRODUCT HIGHLIGHTS Low Power The AD876 at 160 mW consumes a fraction of the power of presently available 8- or 10-bit, video speed converters. Powerdown mode and single-supply operation further enhance its desirability in low power, battery operated applications such as electronic still cameras, camcorders and communication systems. Very Small Package The AD876 comes in a 28-lead SOIC, 28-lead SSOP, and 48- lead surface mount, thin quad flat package. The TQFP package is ideal for very tight, low headroom designs. Digital I/O Functionality The AD876 offers three-state output control. Pin Compatible Upgrade Path The AD876 offers the option of laying out designs for eight bits and migrating to 10-bit resolution if prototype results warrant.
