概述

Description

The AD5302BRMZ is a dual 8-bit multiplying digital-to-analog converter (DAC) from Analog Devices. It provides two voltage-output DAC channels (OUTA and OUTB) that are programmed via a serial interface (SPI-compatible). The outputs are proportional to an external reference applied to VREF, giving a programmable full-scale range. It operates from a single supply (typically 2.7–5.5 V) and comes in an 8-pin MSOP (BRMZ) package,RoHS-compliant. Key features include monotonic 8-bit DAC cores, low power, and the ability to update both channels simultaneously (via a LDAC-like control). Typical applications are precision level setting, calibration, programmable gain, and waveform generation in instrumentation and control systems. For exact specs (Vref range, accuracy, offset, noise, settling), and pinout, consult the AD5302 datasheet on Analog Devices’ website.

Features

AD5302BRMZ is a dual, 8‑bit digital potentiometer with I2C serial interface. Key features:
- Two independent potentiometer channels (two wipers, 256 steps each)
- I2C compatible serial interface (write-only access to wiper positions)
- End-to-end resistance options per variant (fixed per device; consult datasheet for exact value)
- Potentiometer can operate as a standard potentiometer or as a rheostat
- Wiper settings stored in volatile registers (and optionally non-volatile memory on suitable variants)
- Incremental and non‑incremental write modes
- Low power CMOS device; wide supply range (typical 2.7 V to 5.5 V)
- Industrial temperature range (typical -40°C to +125°C)
- Small 8‑lead package (MSOP/SOIC variants) in BRMZ family
- Applications: gain/offset adjustment, sensor calibration, DAC/ADC front ends, audio, and instrumentation
Note: exact end-to-end resistance (RAB) and voltage/NR (readback) capabilities vary by part variant; please refer to the AD5302 datasheet for precise specifications.

Package

MSOP-8 (8-lead MSOP) package, RoHS-compliant.

Pinout

- Pin count: 8 pins.
- Function: Dual 8-bit digital potentiometer with a serial interface (I2C-compatible). It provides two potentiometer sections (A–B–W per section) whose wiper positions are digitally programmable to adjust analog signals.

Manufacturer

Manufacturer: Analog Devices, Inc. (Analog Devices).
What kind of company: An American multinational semiconductor company that designs and manufactures analog, mixed-signal, and digital signal processing integrated circuits.

Application

AD5302BRMZ is a dual, 8-bit DAC with an I2C-compatible interface. Common applications include: programmable gain/offset in instrumentation and data acquisition, programmable attenuators, analog control loops, calibration and test equipment, waveform generation, servo/motor control, audio level control in consumer electronics, and sensor conditioning networks.

Equivalent

The AD5302BRMZ is a dual 8-bit multiplying DAC (MDAC) with an I2C-like serial interface in MSOP-8. Closest equivalents (Analog Devices MDAC family): AD5300, AD5320, AD5322. For SPI options (not I2C): TI DAC7560/ DAC7556/ DAC7558 and Microchip MCP49x8 series. Exact pinout, reference, and voltage ranges vary; use a cross‑reference tool for a true drop‑in replacement.
