Product Overview

The AD7846JNZ is a LC²MOS 16-bit voltage output Digital-to-analog Converter (DAC) constructed with the Analog Devices Inc, process. It has VREF+ and VREF- reference inputs and an on-chip output amplifier. This can be configured to give unipolar output range or bipolar output ranges. 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-bit of resolution. This architecture ensures 16-bit monotonicity. Excellent integral linearity results from tight matching between the input offset voltages of the two buffer amplifiers. In addition to the excellent accuracy specifications, the AD7846 also offers a comprehensive microprocessor interface. R/W and CS allow writing to and reading from the I/O latch. This the read-back function, which is useful in ATE applications.
  • Microprocessor compatible with read-back capability
  • Multiplying capability
  • Low power
