Frequently Asked Questions
How does LMH6642QMFX/NOPB achieve rail-to-rail output on a single 3.3 V supply?
The rail-to-rail output stage allows the output voltage to swing within millivolts of both the positive and negative supply rails. On a single 3.3 V supply, this provides nearly 3.3 V of usable output range, compared to roughly 1 V less with conventional amplifiers. The 75 mA output current maintains this swing even when driving 50 Ω or 75 Ω load impedances typical in video and RF front-end circuits.
For a 130 MHz bandwidth application, how does LMH6642QMFX/NOPB perform in a unity-gain buffer configuration?
At unity gain, the -3 dB bandwidth is approximately 130 MHz, making it suitable for buffering high-frequency analog signals up to 100 MHz without significant attenuation. The 46 MHz small-signal bandwidth figure applies under specific gain conditions, while the full 130 MHz spec represents the gain-bandwidth product available for closed-loop designs with gains of 2 to 5 targeting 25–65 MHz signal bandwidths.
Which video applications can use LMH6642QMFX/NOPB to drive standard 75 Ω cable loads?
Composite video signal distribution, CCTV camera output drivers, and SD-SDI line drivers benefit from the 75 mA output current and 130 MHz bandwidth. With a 75 Ω series termination resistor and 75 Ω load, the amplifier delivers the 1 Vpp composite video signal with adequate slew rate and low distortion. The SOT-23 5-pin package fits densely populated video distribution PCBs where space is limited to less than 10 mm².
How does the 74 dB minimum CMRR help when LMH6642QMFX/NOPB is used in a differential signal receiver?
A 74 dB minimum CMRR means the amplifier rejects common-mode interference signals by a factor of over 5000:1, so a 1 V common-mode noise signal on both inputs appears as only 0.2 mV at the output. This is essential in industrial environments where ground noise and supply ripple at 50 Hz to several MHz can couple onto sensor or communication signal lines, ensuring the 46 MHz signal path remains clean in 3.3 V or 5 V ADC front-end stages.
