ADA4807-1ARJZ-R7

Overview

The ADA4807-1ARJZ-R7 is a single-channel, low noise, rail-to-rail input and output voltage feedback amplifier manufactured by Analog Devices. It features a 180 MHz bandwidth, 225 V/µs slew rate, and 3.1 nV/√Hz input voltage noise density at 100 kHz. The device operates on supply voltages ranging from 2.7 V to 11 V with a quiescent current of 1 mA per amplifier. It includes an active low power-down DISABLE pin and is housed in a 6-lead SOT-23 package.

Feature Summary

• Rail-to-rail input and output capability maximizes dynamic range across the full supply voltage range.
• Integrated active low power-down DISABLE pin enables rapid transition between enabled operation and ultra-low standby current.
• Low input offset voltage and drift ensure high DC precision for accurate signal conditioning.

Applications

• High resolution analog-to-digital converter (ADC) drivers
• Portable and battery-powered instruments and systems
• High component density data acquisition systems

Procurement Notes

Verify the specific ordering suffix ARJZ-R7 against the manufacturer's official documentation to confirm the exact package type, tape and reel specifications, and environmental compliance status. Ensure the intended application environment falls within the specified operating temperature range and supply voltage limits defined in the datasheet.

Selection Notes

Select this component when designing circuits that require simultaneous low noise performance, high speed, and low power consumption. The rail-to-rail I/O functionality makes it suitable for single-supply applications where maximizing signal swing is critical. Consider the integrated disable feature for systems requiring power management capabilities.

Part Context

This part belongs to the ADA4807 family of amplifiers, which also includes dual (ADA4807-2) and quad (ADA4807-4) variants. All members share identical electrical characteristics but differ in channel count and packaging options such as MSOP, LFCSP, and TSSOP. The ADA4807-1 specifically provides a single amplifier solution in compact surface-mount packages.

Replacement Considerations

Direct functional replacements within the same family include the ADA4807-2ARMZ-R7 (dual channel) or ADA4807-4 (quad channel), provided the additional channels are acceptable. Verify pin compatibility and thermal dissipation requirements when substituting with different package types.
