MAX40242 20V, Low Input Bias-Current, Low-Noise, Dual Op Amp General Description Benefits and Features The MAX40242 provides a combination of high voltage, 2.7V to 20V Single Supply or 1.35V to 10V Dual low noise, low input bias current in a dual channel and Supplies features rail-to-rail at the output. 2pA (Max) Input Bias Current This dual amplifier operates over a wide supply voltage 5nV/Hz Input Voltage Noise range from a single 2.7V to 20V supply or split 1.35V 10MHz Bandwidth to 10V supplies and consumes only 1.2mA quiescent 8V/s Slew Rate supply current per channel. Rail-to-Rail Output The MAX40242 is a unity-gain stable amplifier with a gain-bandwidth product of 10MHz. The device outputs Integrated EMI Filters drive up to 200pF load capacitor without any external 1.2mA Supply Current per Amplifier isolation resistor compensation. Tiny, 0.85mm x 1.65mm 8-WLP The MAX40242 is available in 8-thin wafer-level packages (WLPs) and is rated for operation over the -40C to +125C automotive temperature range.
