ADA4807-1AKSZ-R7

Overview

The ADA4807-1AKSZ-R7 is a single-channel, low noise, rail-to-rail input and output voltage feedback amplifier from Analog Devices. It combines high speed with DC precision, featuring a 180 MHz bandwidth and 225 V/μs slew rate while consuming only 1 mA per amplifier. The device offers ultra-low input voltage noise of 3.1 nV/√Hz at 100 kHz and excellent distortion performance. It includes an active low power-down disable pin to reduce current consumption to approximately 2 μA. Fully specified for +3 V, +5 V, and ±5 V supplies, it operates over the industrial temperature range of −40°C to +125°C.

Feature Summary

• Ultra-low input voltage noise density of 3.1 nV/√Hz combined with high speed performance.
• Rail-to-rail input and output capabilities allowing full signal swing across the supply range.
• Active low power-down mode via the DISABLE pin significantly reduces quiescent current consumption.
• High slew rate and fast settling time suitable for driving high-speed data converters.

Applications

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

Procurement Notes

Verify the specific package suffix AKSZ corresponds to the 6-Lead SC70 package as indicated by the model designation. Confirm that the -R7 suffix denotes reel packaging. Ensure the ordering part number matches the exact revision required for your design, as specifications are subject to change without notice. Cross-reference the manufacturer's official datasheet for the most current electrical characteristics and mechanical dimensions before finalizing procurement.

Selection Notes

Select this amplifier when both low noise and high bandwidth are critical requirements in a single-supply or dual-supply environment. The integrated disable feature makes it suitable for power-sensitive applications requiring dynamic power scaling. Consider the 6-Lead SC70 package for space-constrained designs. Evaluate the trade-off between the 1 mA quiescent current and the 3.1 nV/√Hz noise floor against other amplifiers if lower power consumption is prioritized over ultra-low noise.

Part Context

The ADA4807-1 is part of the ADA4807 family, which also includes dual (ADA4807-2) and quad (ADA4807-4) variants. This family is designed to provide a scalable solution for applications requiring low noise, high speed, and low power consumption. The single-channel configuration allows for independent optimization of individual channels in multi-amplifier systems. All variants share similar electrical characteristics but differ in channel count and package options.

Replacement Considerations

Direct replacements within the same family include the ADA4807-2ARMZ (dual, MSOP) and ADA4807-4ARUZ (quad, TSSOP). For single-channel needs, verify compatibility with other Analog Devices rail-to-rail amplifiers such as the ADA4895 series, ensuring noise, bandwidth, and package constraints are met. Check pinout compatibility if substituting with non-family parts.
