ADA4806-1ARJZ-R2

Overview

The ADA4806-1ARJZ-R2 is a single-channel, voltage feedback operational amplifier featuring rail-to-rail output and three power modes: full power (500 µA), sleep (74 µA), and shutdown (2.9 µA). It provides a 105 MHz bandwidth and 160 V/µs slew rate at 5 V supplies. Key DC specifications include a maximum input offset voltage of 125 µV and drift of 1.5 µV/°C. The device operates on a 2.7 V to 10 V supply range within the -40°C to +125°C industrial temperature range.

Feature Summary

• Supports dynamic power scaling via dedicated Sleep and Shutdown pins to optimize energy consumption in data conversion systems.
• Delivers high-speed performance with rail-to-rail output swing while maintaining low quiescent current consumption.
• Provides excellent DC precision characterized by low input offset voltage and minimal drift over temperature.

Applications

• Precision analog-to-digital converter (ADC) drivers
• Portable and battery-powered instruments
• High channel density data acquisition systems
• Voltage reference buffers

Procurement Notes

Verify the specific R2 suffix against the manufacturer's ordering guide to confirm reel packaging requirements. Ensure the design accommodates the 8-lead SOT-23 thermal characteristics for the intended ambient conditions. Confirm that the application circuit correctly interfaces with the Sleep and Shutdown control logic to utilize the multimode power features effectively.

Selection Notes

Select this component when system constraints require minimizing power dissipation without sacrificing high-speed signal integrity. The multimode capability allows dynamic adjustment of quiescent current based on sampling rates. Verify that the required bandwidth and settling time meet the specific ADC interface requirements under the target supply voltage conditions.

Part Context

This part belongs to the ADA4806-1 series of low-power, high-speed amplifiers designed for portable applications. It utilizes an 8-lead SOT-23 package to save board space. The R2 suffix typically denotes tape and reel packaging configuration as defined by Analog Devices standards.

Replacement Considerations

ADA4806-1ARJZ-R7 is a verified alternative offering identical electrical specifications but packaged in cut tape rather than reel format.
