LMP8603QMMX/NOPB

Instrumentation, Op Amps, Buffer Amps Overview

The LMP8603QMMX/NOPB is a single-channel current sense amplifier from Texas Instruments, designed for automotive applications with AEC-Q100 qualification. It features a wide common-mode voltage range of -22 V to 60 V and supports bidirectional current sensing. The device operates on a supply voltage between 3 V and 5.5 V, consuming 1.5 mA of quiescent current. Key electrical parameters include a gain bandwidth product of 60 kHz, a common-mode rejection ratio of 90 dB, and an input offset voltage of 1 mV. It provides a fixed gain of 100 V/V with a gain error of 0.5%. The component functions within an operating temperature range of -40°C to +125°C and is housed in an 8-pin VSSOP package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'X' indicates tape-and-reel packaging when ordering. Confirm that the Q-designation aligns with required automotive grade specifications for your application. Ensure the VSSOP-8 footprint matches your PCB layout constraints. Check for any recent production lifecycle notices regarding availability status before finalizing procurement plans.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a wide common-mode voltage range including negative values is required alongside bidirectional sensing capabilities. It is suitable for designs needing moderate bandwidth and high accuracy in automotive environments. Consider the fixed gain of 100 V/V for signal conditioning needs without external resistors. Evaluate power consumption requirements against the 1.5 mA quiescent current specification.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LMP8603 family of precision current sense amplifiers. It shares functional similarities with other automotive-grade sensors but is distinct in its specific voltage range and gain configuration. The non-Pb (NOPB) suffix indicates lead-free construction compliant with RoHS standards. It serves as a specialized solution for harsh automotive electrical environments.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The LMP8603QMME/NOPB is a related variant within the same family, though it may differ in specific electrical tolerances or packaging options. Verify pin compatibility and parameter alignment before substitution. No direct cross-manufacturer replacements are confirmed in public documentation.
