LTC2053IMS8#PBF

Instrumentation, Op Amps, Buffer Amps Overview

The LTC2053IMS8#PBF is a precision, rail-to-rail, zero-drift instrumentation amplifier in an 8-lead MSOP package. It operates on single supplies from 2.7V to 5.5V or dual supplies up to ±5.5V. Key electrical characteristics include a typical CMRR of 116dB independent of gain, maximum input offset voltage of 10µV, and average drift below 50nV/°C over the industrial temperature range. Gain is programmable via two external resistors with a formula of 1 + R2/R1. The device draws a typical supply current of 750µA and features a shutdown mode consuming 10µA.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix #PBF indicates lead-free and RoHS compliance status as per manufacturer documentation. Confirm the IMS8 designation corresponds to the 8-lead plastic MSOP package variant. Ensure the 'I' grade matches the required -40°C to 85°C operating temperature range for the target application environment.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when ultra-low offset voltage and drift are critical requirements. The standard LTC2053 version lacks an external clock pin; use the SYNC variant if synchronization to an external system clock is necessary to prevent aliasing. Consider source resistance limitations, as mismatches greater than 10k may introduce DC errors due to internal sampling currents.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LTC2053 family of zero-drift instrumentation amplifiers. It shares architectural similarities with the LTC2053-SYNC but differs by integrating an internal oscillator rather than requiring an external clock signal on Pin 1. The IMS8 package provides a compact surface-mount solution suitable for space-constrained designs compared to larger DFN options.

Instrumentation, Op Amps, Buffer Amps FAQ

How is the gain of the LTC2053IMS8#PBF configured?

The gain is set by two external resistors connected between the RG pin and the inverting input, following the formula Gain = 1 + R2/R1.

What is the function of Pin 1 on the LTC2053IMS8#PBF?

Pin 1 serves as the active-low Enable (EN) pin to control the device's power state, allowing for a shutdown current of 10µA.
