Analog Devices / Maxim Integrated MAX40242 Dual Operational Amplifier

Analog Devices MAX40242 Dual Operational Amplifier combines high voltage, low noise, and 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 external isolation resistor compensation. The MAX40242 is available in 8-thin wafer-level packages (WLPs) and is rated for operation over the -40°C to +125°C automotive temperature range.
