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 minimize external voltage drops. The AD876 can be placed into a standby mode of operation reducing the power below 50 mW. The AD876s 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 AD876s speed, resolution and single-supply operation ideally suit a variety of applications in video, multimedia, imag- ing, high speed data acquisition and communications. The AD876s 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 systems such as color scanners, digital copiers, electronic still cameras and camcorders. The AD876 comes in a space saving 28-lead SOIC and 48-lead 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. Power- down 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....
