The AD876 is a CMOS, 160mW, 10-bit, 20MSPS analog-to-digital converter (ADC). The AD876 has an on-chip input sample-and-hold amplifier. By implementing a multistage pipeline 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 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 output is determined by the A/D converter's control byte.
The AD876 is a CMOS 10‑bit, 20 MSPS analog‑to‑digital converter offered in 28‑lead SOIC, 28‑lead SSOP and 48‑lead TQFP packages. It operates from a single +5 V supply, provides differential nonlinearity of 0.5 LSB, guarantees no missing codes, and includes three‑state digital outputs compatible with +5 V or +3.3 V logic.
The datasheet includes detailed specifications, pin‑function descriptions, absolute maximum ratings, typical performance curves, and application notes on reference input driving, power consumption, and layout considerations. It also provides a theory of operation and example circuits for level shifting and AC‑coupled inputs.
