INA351CDSIDSGR

Instrumentation, Op Amps, Buffer Amps Overview

The INA351CDSIDSGR is a single-channel instrumentation amplifier from Texas Instruments, housed in an 8-pin WSON package. It operates on a supply voltage ranging from 1.8V to 5.5V and consumes a typical quiescent current of 110µA. The device features selectable gain options of 30 V/V or 50 V/V via the GS pin. Key electrical specifications include a typical input offset voltage of 200µV, a common-mode rejection ratio (CMRR) of 95dB, and a -3dB bandwidth of 100kHz at G=10. It supports a specified operating temperature range from -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix IDSGR corresponds to the WSON-8 package variant when sourcing. Confirm that the CDS designation aligns with the required gain settings of 30 or 50 V/V. Ensure the ordering information matches the manufacturer's latest datasheet revisions to avoid discrepancies in pinout or thermal pad connections.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring high precision in small form factors. The integrated resistors eliminate the need for external matching components, reducing bill of materials costs. Consider the 100kHz bandwidth and low noise density for signal conditioning tasks where power efficiency is critical.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the INA351 family of cost and size-optimized instrumentation amplifiers. Unlike other variants such as the ABS series which offers gains of 10 or 20, the CDS variant specifically provides higher gain options of 30 or 50. This makes it suitable for applications requiring greater signal amplification without additional discrete components.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct substitutes within the same family include the INA351ABS series for lower gain requirements. For different package types, the DDF (SOT-23-THN) or RUG (X2QFN) versions of the INA351CDS offer identical electrical performance but require layout adjustments due to differing physical dimensions.
