AD8625ARU

Instrumentation, Op Amps, Buffer Amps Overview

The AD8625ARU is a quad precision JFET input operational amplifier from Analog Devices, housed in a 14-lead TSSOP package. It supports single-supply operation from 5 V to 26 V and dual-supply operation from ±2.5 V to ±13 V. The device features rail-to-rail output capability, low supply current of 630 μA per amplifier, and a gain bandwidth product of 5 MHz. Key electrical characteristics include a maximum offset voltage of 500 μV at 25°C and an input bias current as low as 1 pA.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'RU' confirms the 14-lead TSSOP package configuration. Ensure the component meets industrial temperature range requirements (-40°C to +85°C). Confirm that the ordering part number matches the exact channel count and package style required for the target PCB layout.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when high input impedance and low bias current are critical for minimizing errors in high-impedance source applications. The rail-to-rail output allows for maximum dynamic range in single-supply systems. Consider the 5 MHz bandwidth for applications requiring faster signal settling times compared to older single-supply JFET amplifiers.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the AD862x family of precision low-power single-supply JFET amplifiers. The AD8625 specifically provides four independent amplifiers within a compact surface-mount package. This family is designed to offer a balance of precision, low power consumption, and wide bandwidth suitable for portable and battery-operated instrumentation.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The AD8625ARZ serves as a direct pin-compatible alternative utilizing an 8-pin SOIC package variant if the circuit design accommodates different channel counts or packaging constraints.
