COS1333TRD

The COS1333 (single), COS2333 (dual) and COS4333 (quad) are micro power, zero-drift operational amplifiers operated on 1.8 to 5.5 supplies. COSx333 family use chopper stabilized technique to provide very low offset voltage （less than 30μv maximum）and near zero drift over temperature. Low quiescent supply current of 18μA per amplifier and very low input bias current make the devices an ideal choice for low offset, low power consumption and high impedance applications. Despite their low quiescent current, the COSx333 family provides excellent overall performance and versatility. They have both rail-to-rail input and output range. The output voltage swing extends to within 5mV of each rail, providing the maximum output dynamic range with excellent overdrive recovery. COSx333 family is unity gain stable and has a gain bandwidth product of 350kHz (typical).
