AD5172BRMZ50

Overview

The AD5172BRMZ50 is a dual-channel, 256-position digital potentiometer manufactured by Analog Devices Inc. It employs one-time programmable (OTP) fuse link technology to permanently retain resistance settings after a single programming event. The device features an I2C-compatible interface for control and operates on a single supply voltage ranging from 2.7 V to 5.5 V. Key electrical parameters include a nominal end-to-end resistance of 50 kΩ with a tolerance of ±20%, a temperature coefficient of 35 ppm/°C, and a maximum supply current of 6 µA. The unit is housed in a compact 10-lead MSOP package.

Feature Summary

Dual-channel architecture with 256 tap positions per channel
One-time programmable (OTP) memory using fuse link technology
I2C-compatible serial interface for wiper adjustment
Low power consumption with 6 µA maximum supply current

Applications

Systems calibration requiring permanent factory settings
Replacement for mechanical trimmers in new designs
Transducer adjustment for pressure, temperature, and optical sensors
RF amplifier biasing and gain control

Procurement Notes

Verify the specific resistance value suffix (e.g., 50 for 50 kΩ) against design requirements. Confirm that the OTP programming capability aligns with the application's need for non-volatile storage without EEPROM complexity. Ensure the I2C address configuration supports the system bus topology.

Selection Notes

Select this component when a dual-channel solution with permanent setting retention is required. The 50 kΩ variant offers a balance between noise performance and drive capability. Verify that the external power supply can provide the necessary voltage (5.6 V to 5.8 V) and current (100 mA) if OTP activation is planned during manufacturing.

Part Context

This part belongs to the AD517x family of digital potentiometers, which includes the AD5172 (dual-channel) and AD5173 (dual-channel with extra address pins). The BRMZ50 designation indicates the commercial temperature range, MSOP package, and 50 kΩ resistance value within the broader AD5172 product line.
