INA350ABSIDSGR

Instrumentation, Op Amps, Buffer Amps Overview

The INA350ABSIDSGR is a single-channel instrumentation amplifier from Texas Instruments, housed in an 8-pin WSON package. It operates on a supply voltage ranging from 1.8 V to 5.5 V and supports a specified temperature range of -40°C to +125°C. The device features selectable gain options of G=10 or G=20, controlled via the GS pin. Key electrical parameters include a typical input offset voltage of 200 µV, a typical CMRR of 95 dB, and a quiescent current of 100 µA. It offers a bandwidth of 50 kHz at G=20, a slew rate of 240 mV/µs, and an input bias current of 650 fA.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Selectable gain configuration allows switching between G=10 and G=20 using the Gain Select (GS) pin logic levels.
• Integrated precision matched resistors eliminate the need for external components, reducing bill of materials costs and board space.
• Includes an integrated shutdown option that disables the amplifier to minimize power consumption during idle periods.
• Designed with a three-amplifier architecture optimized for driving low-speed analog-to-digital converters directly.

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

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix DSG corresponds to the 8-pin WSON package when sourcing. Confirm the ABSID variant matches the required gain selection (G=10/G=20). Ensure the operating environment stays within the -40°C to +125°C specification. Check for RoHS compliance status as indicated in official documentation before finalizing procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for designs requiring size and cost optimization alongside low power consumption. It is suitable for replacing discrete instrumentation amplifier implementations built with commodity amplifiers. Consider the 50 kHz bandwidth at G=20 when designing for signal frequency requirements. Verify compatibility with 10-bit to 14-bit ADC systems for optimal performance integration.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the INA350 family of cost and size-optimized instrumentation amplifiers. It shares architectural similarities with the INA351 but differs in gain options and packaging. The INA350 series provides selectable gains across ABS and CDS variants, offering flexibility for various sensor interface applications while maintaining high common-mode rejection ratios.
