MAX40242

20V, Low Input Bias-Current, Low-Noise, Dual Op Amp

Dual Amplifier Offers a Combination of Very Low Bias Current and Low Noise Per Unit of Power


Please check latest availability status for a specific part variant.

Description

The MAX40242 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 MAX40242 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 MAX40242 is available in 8-bump WLP SOT23 and is rated for operation over the -40°C to +125°C automotive temperature range
