MAX44242 Datasheet, PDF (1/11 Pages) Maxim Integrated Products – Low-Noise, Dual Op Amplifier

MAX44242
EVALUATION KIT AVAILABLE
20V, Low Input Bias-Current,
Low-Noise, Dual Op Amplifier
General Description
The MAX44242 provides a combination of high voltage,
low noise, low input bias current in a dual channel and
features rail-to-rail at the output.
This dual amplifier operates over a wide supply voltage
range from a single 2.7V to 20V supply or split ±1.35V
to ±10V supplies and consumes only 1.2mA quiescent
supply current per channel.
The MAX44242 is a unity-gain stable amplifier with a
gain-bandwidth product of 10MHz. The device outputs
drive up to 200pF load capacitor without any external
isolation resistor compensation.
The MAX44242 is available in 8-pin SOT23 and µMAXM
packages and is rated for operation over the -40ºC to
+125ºC automotive temperature range.
