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.
Feature Summary
- True single-supply operation with rail-to-rail output swing
- Precision JFET input stage providing extremely low input bias current
- Unity gain stable design without phase reversal near the positive rail
- Capacitive load stability exceeding 500 pF
Applications
- Photodiode transimpedance amplification
- ATE reference level drivers
- Battery management systems
- Remote sensor signal conditioning including automotive sensors
- Precision active filters
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.
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.
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.
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.
