Description
AD8402ARUZ50 is Analog Devices’ dual 8-bit multiplying digital-to-analog converter (M-DAC). It provides two independent DAC channels; each channel uses an 8-bit digital input and a reference to generate a current output proportional to the input word and reference (Iout ∝ D/256 × IoutFS). The outputs are intended to be converted to a voltage with a precision op-amp (current-to-voltage conversion).
Typical uses include programmable gain control, calibration, waveform generation, and other applications needing two programmable analog levels.
Key points:
- Dual 8-bit multiplying DAC
- Current-output per channel (requires external I-to-V conversion)
- Reference-driven full-scale
- Designed for precision, monotonicity, and relatively fast settling with low glitch
- ARUZ50 indicates a specific package/temperature variant; check the datasheet for exact IoutFS, Vref ranges, supply voltages, timing, and pinout.
For exact specs and wiring details, see the AD8402 datasheet and product page.
