Data Sheet FEATURES 16-bit monotonicity over temperature ±2 LSBs integral linearity error Microprocessor compatible with readback capability Unipolar or bipolar output Multiplying capability Low power (100 mW typical) GENERAL DESCRIPTION The AD7846 is a 16-bit DAC constructed with the Analog Devices, Inc., LC2MOS process. It has VREF+ and VREF− reference inputs and an on-chip output amplifier. These can be configured to give a unipolar output range (0 V to +5 V, 0 V to +10 V) or bipolar output ranges (±5 V, ±10 V). The DAC uses a segmented architecture. The four MSBs in the DAC latch select one of the segments in a 16-resistor string. Both taps of the segment are buffered by amplifiers and fed to a 12-bit DAC, which provides a further 12 bits of resolution.
