HTC8551数据手册HUATECH中文资料规格书

描述 Description

The HTC8551(single) and HTC8552(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(2 μV 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 HTC8551 is available in SC70-5, SOT23-5, MSOP-8 and SOP-8.The HTC8552 is available in MSOP-8 and SOP-8. All versions ae specified for operation from -40 ℃ to +125 ℃.
