The AD660 DACPORT is a complete 16-bit monolithic D/A converter with an on-board voltage reference, double buffered latches and output amplifier. 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 s to within 1/2 LSB for a full-scale step.
