AD7376ARUZ50

Digital Potentiometers Overview

The AD7376ARUZ50 is a single-channel, high-voltage digital potentiometer manufactured by Analog Devices Inc. It features 128 programmable tap positions with a nominal resistance of 50 kΩ and ±30% tolerance. The device operates on a single supply from 4.5 V to 33 V or dual supplies from ±4.5 V to ±16.5 V. It utilizes a 3-wire SPI-compatible serial interface for control and includes a shutdown mode consuming less than 1 µA. Packaged in a 14-lead TSSOP, it supports an extended industrial temperature range of −40°C to +85°C.

Digital Potentiometers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and resistance value. Confirm RoHS compliance status and lead-free specifications directly with the supplier or manufacturer datasheet before procurement.

Digital Potentiometers Selection Notes

Select this component when high voltage handling and solid-state reliability are required. Ensure the system voltage does not exceed the absolute maximum ratings of 33 V single-supply or ±16.5 V dual-supply. Verify that the 50 kΩ resistance value meets the circuit's current and bandwidth requirements.
