ADA4505-4ARUZ-RL

Overview

The ADA4505-4ARUZ-RL is a quad micropower operational amplifier featuring rail-to-rail input and output swings. It operates from a single 1.8 V to 5 V supply or dual ±0.9 V to ±2.5 V supplies. Key electrical parameters include a maximum offset voltage of 3 mV, typical input bias current of 0.5 pA, and supply current of 7 µA per amplifier. The device offers a gain-bandwidth product of 50 kHz, slew rate of 6 mV/µs, and minimum PSRR of 100 dB. It is housed in a 14-lead TSSOP package.

Feature Summary

Zero input crossover distortion achieved through an on-chip charge pump technology that powers the input differential pair.
Rail-to-rail input and output capability providing full common-mode dynamic range without phase reversal.
Very low input bias current and high input resistance suitable for high-impedance sensor interfaces.

Applications

Pulse oximeter red and infrared current sources
Pressure and position sensors
Remote security systems
Medical monitors

Procurement Notes

Verify the specific ordering suffix ARUZ-RL against the manufacturer's official documentation to confirm the 14-lead TSSOP package and reel packaging configuration. Ensure compatibility with industrial temperature specifications before integration into final designs.

Selection Notes

Select this component for applications requiring low power consumption alongside precision signal conditioning. The quad configuration allows multiple channels within a single footprint. Verify that the 50 kHz bandwidth meets the system requirements for signal processing speed.

Part Context

This part belongs to the ADA4505-x family of zero crossover amplifiers designed for battery-powered applications. It addresses errors caused by battery voltage decrease over time while maintaining high CMRR performance across the entire input common-mode voltage range.
