PRODUCT HIGHLIGHTS The AD669 chip includes current switches, decoding logic, an output amplifier, a buried Zener reference and double-buffered latches. The AD669’s architecture insures 15-bit monotonicity over temperature. Integral nonlinearity is maintained at ± 0.003%, while differential nonlinearity is ± 0.003% max. The on-chip output amplifier provides a voltage output settling time of 10 µs to within 1/2 LSB for a full-scale step.
