Overview

The OPA4170AIPW is a quad-channel, low-power operational amplifier designed to operate on a wide supply range from 2.7V to 36V. It features rail-to-rail output performance and an input stage that includes both supply rails, making it highly versatile for diverse signal conditioning tasks. With a quiescent current of only 110uA per channel and integrated RFI filtering, it is optimized for power-sensitive industrial and portable applications.

Why Choose This Part

The device offers an excellent balance of a 1.2 MHz gain bandwidth product and a very low 110uA supply current. Its ability to operate up to 36V while providing rail-to-rail output allows for significant dynamic range in industrial environments. Additionally, the 8pA input bias current and integrated RFI protection ensure high signal integrity when interfacing with high-impedance sources.

Applications

Power Supply Tracking
Used as a tracking amplifier in power supply modules to monitor and adjust output rails.
Current Sensing
Ideal for low-side and high-side current sensing in battery-powered systems due to its wide input common-mode range.
Transducer Amplifiers
Conditions signals from industrial sensors where high supply voltage headroom and low input bias current are required.
Active Filtering
Supports multi-stage active filter designs with four independent channels in a single 14-TSSOP package.

Getting Started

To evaluate this part, utilize a standard 14-pin TSSOP breakout board for breadboarding or prototype on a PCB with decoupled 0.1uF capacitors near the supply pins. Ensure the input signals remain within the 2.7V to 36V supply limits, and refer to the TI Precision Labs training series for standard op-amp configuration best practices.
