描述 Description

ET85001 is a low-voltage (1.8 V to 5.5 V) operational amplifier with rail-to-rail input and output swing capabilities. ET85001 provides a cost-effective solution for space-constrained applications such as smoke detectors, wearable electronics, and small appliances where low-voltage operation and high capacitive-load drive are required. The capacitive-load drive is 500 pF and the resistive open-loop output impedance makes stabilization easier with much higher capacitive-loads. ET85001 features the unity-gain stability and integrated RFI and EMI rejection filter and no-phase reversal in overdrive conditions.ET85001 is specified for the extended industrial / automotive temperature range (-40°C to +125°C). ET85001 is available in SOT23-5/SC70-5/DFN4 packages.
