Overview
The LMH6553MRX/NOPB is a single-channel differential amplifier from Texas Instruments, designed for automotive applications. It operates within a supply voltage range of 4.5 V to 12 V and consumes 33 mA at ±5 V. The device features a common-mode rejection ratio (CMRR) of 82 dB and an input bias current of 95 µA. It supports an operating temperature range from -40°C to +125°C and is housed in an 8-pin HSOIC EP package with tape-and-reel packaging.
Feature Summary
- Automotive-grade qualification for reliable operation in vehicle environments
- High common-mode rejection ratio for accurate signal processing
- Wide operating temperature range suitable for harsh conditions
Applications
- Automotive sensor signal conditioning
- Industrial data acquisition systems
- Medical instrumentation
Procurement Notes
Verify the specific suffix MRX indicates tape-and-reel packaging and HSOIC EP package type. Confirm automotive grade status through official TI documentation. Ensure compatibility with 4.5V to 12V supply rails. Check for RoHS compliance details in the datasheet. Validate pinout against schematic requirements before integration.
Selection Notes
Select this component when automotive reliability and high CMRR are required. Consider the 95 µA input bias current for impedance matching. Evaluate the 33 mA supply current against power constraints. Ensure the 8-pin HSOIC EP package fits the PCB layout. Verify temperature range meets application needs.
Part Context
Part of the LMH6553 series of differential amplifiers. Designed for high-speed applications requiring precise differential signal conversion. Complements other TI linear ICs in signal chain designs. Offers robust performance in noisy environments typical of automotive and industrial settings.
Replacement Considerations
Check for direct pin-compatible alternatives in the LMH655x family. Verify electrical parameters match or exceed original specifications. Ensure package dimensions are identical for board-level replacement. Confirm automotive qualification status if required by the design.
