Overview
The AD8618ARUZ is a quad, rail-to-rail input and output, single-supply CMOS operational amplifier from Analog Devices. It features a gain bandwidth product of 24 MHz, a slew rate of 12 V/µs, and an input offset voltage of 23 µV maximum. The device operates on a single supply ranging from 2.7 V to 5 V with a typical supply current of 1.7 mA per amplifier. It provides high output drive capability of ±150 mA and low input bias current of 0.2 pA typical.
Feature Summary
- Patented trimming technique achieves superior precision without laser trimming
- Rail-to-rail input and output operation enables full signal swing in single-supply systems
- Immune to output phase reversal when input common-mode voltage exceeds the supply rails
Applications
- Barcode scanners
- Battery-powered instrumentation
- Multipole filters
- Photodiode amplification
- Buffering CMOS ADCs and DACs
Procurement Notes
Verify the specific package variant RU-14 (TSSOP) against the required footprint. Confirm that the ordering suffix ARUZ corresponds to the tube packaging format rather than reel options. Ensure the component meets the extended industrial temperature range specifications for the intended operating environment.
Selection Notes
Select this component for applications requiring high output current drive alongside precision DC accuracy. The combination of wide bandwidth and low noise makes it suitable for AC applications. Consider the rail-to-rail I/O capability when interfacing with single-supply digital-to-analog or analog-to-digital converters.
Part Context
This part belongs to the DigiTrim family of precision amplifiers, which includes the AD8615 (single) and AD8616 (dual). The AD8618 specifically integrates four independent channels within a single 14-lead TSSOP package. All members share similar electrical characteristics but differ in channel count and physical pinout configurations.
Replacement Considerations
The AD8616ARZ serves as a dual-channel alternative within the same family. Verify compatibility if reducing channel count is acceptable. No direct quad-channel substitutes are explicitly confirmed in the provided documentation.
