It is manufactured on Analog Devices’ BiMOS II process. This process allows the fabrication of low power CMOS logic functions on the same chip as high precision bipolar linear circuitry. The AD660’s architecture ensures 15-bit monotonicity over time and temperature. Integral and differential nonlinearity is maintained at ± 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. The AD660 has an extremely flexible digital interface. Data can be loaded into the AD660 in serial mode or as two 8-bit bytes. This i...
