Frequently Asked Questions
What is the common-mode rejection ratio (CMRR) of the LMH6551MA?
The LMH6551MA offers a typical CMRR of 80 dB with a guaranteed minimum of 72 dB. This high rejection ratio makes it effective at suppressing common-mode noise and interference in differential signal paths, which is essential for precision ADC driving and instrumentation applications.
What are the typical applications for the LMH6551MA?
The LMH6551MA is designed for high-speed differential signal processing applications including ADC input driving, communications receivers, test and measurement equipment, medical imaging front-ends, and industrial data acquisition systems. Its voltage-feedback architecture and high CMRR make it especially suitable for wideband differential amplification tasks.
What is the input offset voltage specification of the LMH6551MA?
The LMH6551MA has a maximum input offset voltage of 6000 µV (6 mV). This parameter is important for DC accuracy in signal chain designs. For applications requiring tighter offset performance, external trimming or auto-zero techniques may be employed alongside this device.
Is the LMH6551MA RoHS compliant?
Based on available data, the LMH6551MA is listed as non-Pb-free (Pbfree Code: No), meaning it may contain lead in its packaging. Designers working on RoHS-compliant designs should verify the specific variant and packaging options with Texas Instruments or consult an authorized distributor for compliant alternatives.
