The AD876 comes in a space saving 28-lead SOIC and 48-lead The AD876 is a CMOS, 160 mW, 10-bit, 20 MSPS analog-to- thin quad flatpack (TQFP) and is specified over the commercial digital converter (ADC). The AD876 has an on-chip input (0°C to +70°C) temperature range. sample-and-hold amplifier. By implementing a multistage pipe- lined architecture with output error correction logic, the AD876
