BCT8321中文资料1MHz, 60uA, Rail-to-Rail I/O CMOS Operational Amplifiers数据手册Broadchip规格书

描述 Description

The BCT83XX is low cost, rail-to-rail input and output voltage feedback amplifiers. It has a wide input common-mode voltage range and output voltage swing, and take the minimum operating supply voltage down to 2.1V. The maximum recommended supply voltage is 5.5V. It’s specified over the extended -40°C to 85°C temperature range.

BCT83XX provides 1MHz bandwidth at a low current consumption of 60uA per amplifier. Very low input bias currents of 10pA enable BCT83XX to be used for integrators, photodiode amplifiers, and piezoelectric sensors. Rail-to-rail input and output are useful to designers for buffering ASIC in single-supply systems. Applications for this series of amplifiers include safety monitoring, portable equipment, battery and power supply control, and signal conditioning and interfacing for transducers in very low power systems. The BCT83XX comes in the Green SOT23-5/SOP8 /SOP14 packages.
