INA351ABSIDSGR

Instrumentation, Op Amps, Buffer Amps Overview

The INA351ABSIDSGR is a single-channel instrumentation amplifier from Texas Instruments, housed in an 8-pin WSON package measuring 2mm by 2mm. 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 10 or 20, controlled via the GS pin. Key electrical specifications include a maximum input offset voltage of 1.3mV, a typical common-mode rejection ratio of 95dB, and a slew rate of 200mV/µs. It supports a wide operating temperature range from -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Selectable gain architecture allows configuration for gains of 10 or 20 through the gain select pin.
• Integrated reference buffer provides unity-gain follower capability for direct connection to reference voltages.
• Shutdown functionality enables significant power reduction when the amplifier is not in active use.
• Space-saving ultra-small package design reduces board area requirements compared to discrete solutions.

Instrumentation, Op Amps, Buffer Amps Applications

• Bridge network sensing
• Differential to single-ended conversion
• Weigh scale systems
• Analog input modules

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix DSGR corresponds to the WSON-8 package with tape-and-reel shipping format. Confirm that the ABS grade meets the required offset voltage and gain error tolerances for your application. Ensure the gain select pin logic levels align with your system's control signals. Check for any recent documentation updates regarding thermal characteristics or recommended operating conditions.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Choose this component when size and low power consumption are critical constraints alongside moderate precision requirements. The fixed internal resistors eliminate the need for external gain-setting components, simplifying the bill of materials. Consider the available gain options of 10 or 20 against your signal conditioning needs. Evaluate the shutdown feature if battery life is a primary design driver.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the INA351 family of cost and size-optimized instrumentation amplifiers. It shares architectural similarities with other members like the INA351CDS but differs in gain settings and performance grades. The family targets applications requiring integration of precision amplification into compact, low-power designs without sacrificing essential signal integrity metrics.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

INA351ABSDDGR offers the same electrical characteristics and gain options in an SOT-23-THN package. INA351ABSRUG provides identical performance in a 10-pin X2QFN package. Verify package dimensions and pinout compatibility before substituting these alternatives.
