概述

Description

AD8402ARUZ50 is a dual 8-bit multiplying DAC (MDAC) from Analog Devices. It provides two independent 8-bit MDAC channels, converting a digital word into an analog output that is the product of the digital code and an external reference. It supports a parallel data input with a common latch and can be configured for voltage or current output via external circuitry. The ARUZ50 suffix indicates the RoHS-compliant, lead-free package with industrial temperature range. Typical uses include programmable gain/attenuation, automated test equipment, calibration, and digitally controlled analog signals. For exact specs (reference range, output ranges, settling time, INL/DNL, supply voltages), refer to the AD8402 datasheet and packaging documentation.

Features

Here are the typical features of AD8402ARUZ50 (dual, 12-bit multiplying DAC):
- Dual 12-bit multiplying DAC cores
- Current-output (Iout) with external resistor/op-amp to convert to voltage
- External reference input for full-scale control
- SPI-compatible serial interface (SCLK, SDI, CS) with LDAC for simultaneous updates
- Single-supply operation (typical 5 V) and wide operating range
- Industrial temperature range: -40 °C to +85 °C
- Monotonic over full code range
- Fast settling time (microseconds range)
- Low glitch energy on code changes
- 8-pin package (ARUZ50), RoHS-compliant (package/marking specifics per ADI)
Common applications: programmable gain/attenuation, precision control, waveform generation, instrumentation DAC outputs. For exact electrical specs (IFS range, full-scale current, exact interfaces, leakage, and guarantees), please consult the latest AD8402 datasheet.

Package

AD8402ARUZ50 is in an 8-lead Small Outline IC package (SOIC-8), RoHS-compliant lead-free variant.
