概述

Description

AD5245BRJZ50-RL7 is a dual digital potentiometer from Analog Devices. It provides two 50 kΩ end-to-end potentiometer networks whose wiper positions are programmable via an I2C-compatible interface. Each channel offers 256 wiper steps (8-bit resolution), enabling precise programmable gain, attenuation, or bias in analog circuits. The device is designed for low power and is suitable for applications such as adjustable gain stages, sensor calibration, and programmable references. The RL7 suffix indicates tape-and-reel packaging, and BRJZ denotes the specific package/revision used by Analog Devices. For exact electrical specs (supply range, temperature range, current consumption, and register map) consult the AD5245 data sheet.

Features

Here are the typical features of AD5245BRJZ50-RL7 (Analog Devices):
- Dual I2C-controlled digital potentiometers
- End-to-end resistance: 50 kΩ per potentiometer
- 8-bit wiper resolution (256 programmable positions) per channel
- Optional nonvolatile memory to retain last wiper setting
- Wide operating voltage: typically 1.8 V to 5.5 V
- Industrial temp range: -40°C to +125°C
- Low power consumption with standby/shutdown support
- Small RoHS-compliant package (8-lead variant)
Note: exact specifications (interfaces, timing, accuracy, and NV behavior) should be confirmed in the official datasheet for precise design parameters.

Package

SOIC-8 (8-pin Small-Outline IC) package.

Pinout

- Pin count: 8 pins (8-pin package).
- Function: 50 kΩ I2C digital potentiometer with terminals A, B, W; power pins (VDD, GND); I2C interface pins (SCL, SDA) and a control/enable pin (SHDN/CS). The wiper position (W) is programmable via I2C, providing a variable resistor between A and B.

Manufacturer

- Manufacturer: Analog Devices, Inc. (ADI)
- What kind of company: An American multinational semiconductor company that designs and manufactures analog, mixed-signal, and DSP ICs used across industrial, automotive, communications, and consumer markets.
