INA351CDSIDDFR

Instrumentation, Op Amps, Buffer Amps Overview

The INA351CDSIDDFR is a single-channel instrumentation amplifier from Texas Instruments, housed in an SOT-23-8 surface-mount package. It operates on a supply voltage range of 1.8 V to 5.5 V with a typical quiescent current of 110 uA. Key electrical specifications include a 100 kHz bandwidth, 200 mV/us slew rate, and 95 dB common-mode rejection ratio. The device features low input bias current (650 fA), low offset voltage (200 uV), and 36 nV/sqrt Hz input voltage noise density. It provides a fixed gain of 1 V/V with 0.02% gain error and supports operation from -40 C to +125 C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the complete part number including suffixes against official Texas Instruments documentation to ensure correct package type and temperature grade. Confirm RoHS compliance status through manufacturer datasheets. Cross-reference Mouser numbers for accurate identification. Ensure ordering specifications match required operational parameters before procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when fixed unity gain is required alongside ultra-low power constraints. Compare against selectable-gain variants if adjustable amplification is needed. Verify that the SOT-23-8 package fits the design constraints. Check thermal performance requirements against the specified operating temperature range.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the INA351 series of instrumentation amplifiers designed for high-precision applications. It shares architectural similarities with other low-power amplifiers but offers specific trade-offs between bandwidth, power, and precision. The series targets applications requiring small form factors without sacrificing signal integrity.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

INA350CDSIDDFR offers selectable gain but lower CMRR. INA351CDSIDSGR uses WSON-8 packaging instead of SOT-23-8.
