INA827AIDGKR

Instrumentation, Op Amps, Buffer Amps Overview

The INA827AIDGKR is a wide supply range, rail-to-rail output instrumentation amplifier manufactured by Texas Instruments. It operates on a single supply voltage ranging from 2.7 V to 36 V or dual supplies up to ±18 V. The device features a fixed minimum gain of 5 V/V and supports gains up to 1000 V/V via an external resistor. Key electrical characteristics include a maximum input offset voltage of 150 µV, a typical common-mode rejection ratio (CMRR) of 95 dB at a gain of 1000, and a bandwidth of 1 MHz. It functions within a temperature range of -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Provides rail-to-rail output swing capability for maximum dynamic range in low-voltage systems.
• Features a wide single-supply operating range from 2.7 V to 36 V.
• Offers high precision with low input offset voltage and high common-mode rejection.

Instrumentation, Op Amps, Buffer Amps Applications

• Industrial process control sensor signal conditioning
• Medical equipment data acquisition systems
• Battery-powered measurement devices

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'AIDGKR' to confirm the A-grade accuracy class, VSSOP-8 package, and tape-and-reel packaging format. Ensure compatibility with the required gain setting resistor and supply voltage constraints during procurement validation.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a fixed minimum gain of 5 V/V is acceptable and rail-to-rail output is required. It is suitable for applications needing wide supply voltage flexibility and high CMRR. Compare against the INA826 if adjustable gain starting from 1 V/V is necessary instead of the fixed minimum gain structure.

Instrumentation, Op Amps, Buffer Amps Part Context

The INA827 belongs to the INA82x family of instrumentation amplifiers from Texas Instruments. It shares the VSSOP-8 surface-mount package with other members like the INA826 but differs in its internal architecture that enforces a minimum gain of 5 V/V. This distinguishes it from general-purpose instrumentation amplifiers that allow lower gain settings.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The INA826AIDGKR is a functional alternative within the same family, offering adjustable gain starting from 1 V/V. For cross-manufacturer replacement, the AD8226ARMZ from Analog Devices provides similar wide supply range and rail-to-rail output specifications.
