Instrumentation, Op Amps, Buffer Amps FAQ

Does the LTC6256CMS#PBF support driving capacitive loads?

Yes, the device utilizes C-Load technology, allowing it to drive up to 100nF capacitive loads in a unity gain configuration without oscillation.

How does the shutdown function affect the output state?

When the SHDN pin is pulled low, the amplifier enters shutdown mode, reducing supply current to less than 7µA. The output enters a high resistance state, which is suitable for multiplexer applications.

What is the input voltage range relative to the supply rails?

The inputs can extend 100mV beyond either the positive or negative supply rail, enabling true ground sensing even with single-supply operation.
