LMP8603MMX/NOPB

Instrumentation, Op Amps, Buffer Amps Overview

The LMP8603MMX/NOPB is a single-channel current sense amplifier from Texas Instruments, designed for bidirectional current monitoring in automotive and industrial systems. It features a fixed gain of 100 V/V, enabling precise signal amplification for analog-to-digital converter interfacing. The device supports an input common-mode voltage range of -22 V to 60 V while operating on a supply voltage between 3 V and 5.5 V. Key electrical specifications include a gain bandwidth product of 60 kHz, a common-mode rejection ratio of 90 dB, and a maximum gain error of 0.5%. It draws 1.5 mA of quiescent current and operates within a temperature range of -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix MMX against official datasheets to confirm package type and tape-and-reel configuration. Ensure the component meets AEC-Q100 requirements if used in automotive designs. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm that the operating temperature range aligns with system thermal constraints before finalizing procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a fixed 100 V/V gain is required for bidirectional current sensing applications. It is suitable for systems requiring operation at common-mode voltages up to 60 V with a 3 V to 5.5 V supply. Consider the 60 kHz bandwidth and 1.5 mA quiescent current for power and speed constraints. Verify that the VSSOP-8 package fits the PCB layout requirements.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the LMP8603 series of precision current sense amplifiers. It shares architectural similarities with the LMP8602 but offers a higher fixed gain of 100 V/V compared to the LMP8602's 50 V/V. The Q suffix indicates automotive-grade qualification, ensuring enhanced manufacturing controls and defect detection methods suitable for demanding environments.
