Overview
The AD8630WARZ-R7 is a quad, zero-drift operational amplifier from Analog Devices, housed in a 14-lead SOIC package. It features rail-to-rail input and output swing with a gain-bandwidth product of 2.5 MHz and a slew rate of 1 V/µs. The device operates on a single supply ranging from 2.7 V to 5 V (or ±1.35 V to ±2.5 V dual). Key electrical characteristics include an input offset voltage of 1 µV, input bias current of 300 pA maximum, and supply current of 4.4 mA. It offers high CMRR and PSRR of 140 dB and 130 dB respectively, with an operating temperature range of -40°C to +125°C.
Feature Summary
- Combines auto-zeroing and chopping technology to eliminate 1/f noise and minimize offset drift.
- Provides rail-to-rail input and output swing for maximizing signal-to-noise ratio.
- Features very low input bias current and ultralow offset voltage for high precision.
- Includes overload recovery time optimization for fast settling after saturation.
Applications
- Automotive sensors
- Pressure and position sensors
- Strain gage amplifiers
- Medical instrumentation
- Thermocouple amplifiers
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm package type and automotive qualification status. Ensure the component matches the required pin configuration and thermal characteristics for the target application environment. Cross-reference the datasheet revision to validate all electrical parameters before final integration.
Selection Notes
Select this component when system requirements demand minimal offset voltage drift over wide temperature ranges without external trimming. The quad configuration is suitable for multi-channel applications requiring matched performance. Verify that the 2.5 MHz bandwidth meets the signal frequency requirements and that the 14-lead SOIC package fits the PCB layout constraints.
Part Context
This part belongs to the AD8628/AD8629/AD8630 family of zero-drift amplifiers. The AD8630 specifically provides four independent channels within a single package. The 'W' suffix indicates automotive qualification, while 'R7' denotes tape and reel packaging. It shares core topology with the AD8628 and AD8629 but differs in channel count and package options.
Replacement Considerations
Direct substitutes within the same family include AD8630ARZ and AD8630ARUZ. Verify package compatibility and electrical parameter alignment when considering these alternatives.
