ADA4505-1ACBZ-R7

Overview

The ADA4505-1ACBZ-R7 is a single-channel micropower operational amplifier from Analog Devices, featuring rail-to-rail input and output swings. It operates on a single supply of 1.8 V to 5 V or dual supplies of ±0.9 V to ±2.5 V. Key electrical parameters include a maximum offset voltage of 3 mV, typical input bias current of 0.5 pA, and supply current of 10 μA per amplifier. The device offers a gain-bandwidth product of 50 kHz, slew rate of 6 mV/µs, and PSRR of 100 dB minimum.

Feature Summary

Rail-to-rail input and output capability with zero input crossover distortion
Ultra-low power consumption suitable for battery-powered applications
High common-mode rejection ratio (CMRR) performance across the full input range
Very low input bias current utilizing specialized CMOS technology

Applications

Pulse oximeter red and infrared current sources
Pressure and position sensors
Remote security systems
Medical monitors
Battery-powered consumer equipment

Procurement Notes

Verify the specific package type and tape-and-reel configuration against the official ordering guide before procurement. Confirm that the component meets the required industrial temperature specifications for your application environment. Ensure compatibility with existing PCB footprints for the 6-ball WLCSP package.

Selection Notes

Select this component when designing low-voltage, battery-operated circuits requiring high precision without external regulation. The integrated charge pump eliminates crossover distortion, making it superior to standard rail-to-rail amplifiers in maintaining signal integrity near supply rails. Consider the low supply current for extended battery life requirements.

Part Context

This part belongs to the ADA4505-x family of micropower amplifiers, which includes dual and quad variants. The family is designed to address errors caused by battery voltage decay over time. It shares core architectural features with the AD8505 series but is optimized for specific cost and performance targets within the zero crossover distortion category.
