PRODUCT DESCRIPTION
The AD871 is a monolithic 12-bit, 5 MSPS analog-to-digital converter with an on-chip, high performance track-and-hold amplifier and voltage reference. The AD871 uses a multistage differential pipelined architecture with error correction logic to provide 12-bit accuracy at 5 MSPS data rates and guarantees no missing codes over the full operating temperature range. The AD871 is a redesigned variation of the AD872 12-bit, 10 MSPS ADC, optimized for lower noise in applications requiring sampling rates of 5 MSPS or less. The AD871 is pin compatible with the AD872, allowing the parts to be used interchangeably as syst……
