LN8544

LN8541/LN8542/LN8544 1.1MHz Rail-To-Rail I/O CMOS Operational Amplifier ■ Description The LN8541、LN8542、LN8544 （single channel, dual channel, four channel ）are rail-to-rail input and output voltage feedback amplifier offering low cost. It has a wide input common-mode voltage range and output voltage swing, and takes the minimum operating supply voltage down to 2.1V and the maximum recommended supply voltage is 5.5V. All are specified over the extended –40°C to +125°C temperature range. The series of LN854X provides 1.1MHz bandwidth at a low current consumption of 42µA per amplifier. Very low input bias currents of 0.5pA, enable LN8541 to be used for integrators, photodiode amplifiers, and piezoelectric sensors. Rail-to-rail inputs and outputs are useful to designers buffering ASIC in single-supply systems. Applications for these amplifiers include safety monitoring, portable equipment, battery and power supply control, and signal conditioning and interfacing for transdu...
