概述

Description

AD8402ARUZ1 is an Analog Devices digital-to-analog converter (DAC) — specifically a dual DAC device. It receives digital data via a serial interface (SPI-like) and outputs two precision analog voltages. The “ARUZ1” suffix denotes the RoHS-compliant packaging variant and the specific package and temperature range.
Key points:
- Dual DAC: two independent output channels.
- Serial interface: convenient microcontroller or DSP control (SPI-compatible).
- Intended uses: precision calibration, instrumentation, control loops, and other applications needing programmable analog signals.
- Features typically include: buffered/drive-capable outputs, programmable voltage ranges (often reference-driven), and parameters such as settling time and linearity as specified in the datasheet.
For exact specifications (bit resolution, output range, reference requirements, power supply, settling time, noise, and package details), refer to the AD8402 datasheet and the ARUZ1 packaging guide.

Features

AD8402ARUZ1 is a dual 12-bit multiplying DAC. Key features typically include:
- Dual 12-bit multiplying DACs (two MDAC channels in one package)
- External reference input to set full-scale range
- Buffered voltage output (or current output with external buffer)
- Monotonic operation over all codes
- Fast settling time and low glitch impulse
- Wide supply voltage range with low power consumption
- Small 8-pin package (ARUZ1 family) and RoHS-compliant
Note: exact specs (Vref range, INL/DNL, typical/maximum settling time, temperature range) are in the official datasheet.

Package

8-pin surface-mount Small-Outline Integrated Circuit (SOIC) package; RoHS-compliant.

Pinout

- Pin count: 16 pins (16-lead package)
- Function: Dual 8-bit multiplying digital-to-analog converter (two independent DAC channels) with current output (Iout) and a reference input.

Manufacturer

- Manufacturer: Analog Devices, Inc. (Analog Devices, ADI).
- What kind of company: A global semiconductor company that designs, manufactures, and sells analog, mixed-signal, and DSP integrated circuits (e.g., data converters, amplifiers, sensors).

Application

Common application areas for AD8402ARUZ1 (a dual digital potentiometer/dac) include:
- Calibration and trimming of instrumentation and ADC/DAC front ends
- Programmable gain/attenuation and offset in amplifiers
- Digitally controlled references and bias networks
- Programmable attenuators in audio, RF, and measurement systems
- Automatic gain control and level setting in test equipment
- Sensor conditioning and temperature compensation
- Servo/motor-control bias networks
(Note: use as a digitally controlled resistor network in analog signal paths.)

Equivalent

Direct equivalents depend on specs. Please provide: end-to-end resistance (RAB), number of wipers (dual), interface (I2C/SPI), supply voltage range, and package. Common substitutes for dual 8‑bit digipots include Microchip MCP41/42/MCP4x families (SPI), TI DS180x/DS186x series, and Renesas digipots.
