HTC8581XT5/R6

HTC8581，HTC8582 Data Sheet High-Precision, Rail-to-Rail I/O Operational Amplifier General Description The HTC8581(single) and HTC8582(dual) are high-precision, low-quiescent current amplifier which can offer high input impedance and rail-to-rail input and output. The amplifier uses auto-zeroing techniques to provide low offset voltage(25μV type) and near zero-drift over time and temperature. Either single or dual supplies can be used in the range from 2.3V to 5.5V (±1.15V to ±2.75V) The HTC8581 is available in SC70-5,SOT23-5, MSOP-8 and SOP-8.The HTC8582 is available in MSOP-8 and SOP-8. All versions ae specified for operation from -40 ℃ to +125 ℃.
