TP5552-VR Ultra Low Noise, 3.5MHz, RRIO, Zero-Drift Dual Op-amps

　　The family of the amplifier are single/dual/quad chopper-stabilized zero-drift operational amplifiers optimized for single or dual supply operation from 1.8 V to 5.5 V and±0.9 V to±2.75 V.TP555X features very low input offset voltage and low noise with no 1/f noise corner down to 0.1 Hz.The TP555X is designed to have ultra-low offset voltage and offset temperature drift,wide gain bandwidth and rail-to-rail input/output swing while minimizing power consumption.This TP555X family can provide very low offset voltage(max 5μV)and near-zero drift over time and temperature with excellent CMRR and PSRR.The TP5551(single version)is available in SOT23-5,and SOP8 packages.The TP5552(dual version)is offered in MOSP8,SOP8 package.The TP5554(quad version)is available in TSSOP14,SOP14 package.All versions are specified for operation from−40°C to 125°C.
