LT1801 80MHz、25V/μs、低功率、轨至轨输入和输出精准运算放大器
The LT™1801/LT1802 are dual/quad, low power, high speed rail-to-rail input and output operational amplifiers with excellent DC performance. The LT1801/LT1802 feature reduced supply current, lower input offset voltage, lower input bias current and higher DC gain than other devices with comparable bandwidth.
Typically, the LT1801/LT1802 have an input offset voltage of less than 100µV, an input bias current of less than 50nA and an open-loop gain of 85 thousand.
The LT1801/LT1802 have an input range that includes both supply rails and an output that swings within 20mVof either supply rail to maximize the signal dynamic range in low supply applications.
The LT1801/LT1802 maintain their performance for supplies from 2.3V to 12.6V and are specified at 3V, 5V and ±5V supplies. The inputs can be driven beyond the supplies without damage or phase reversal of the output.
The LT1801 is available in the MS8, SO-8 and the 3mm x 3mm x 0.8mm dual fine pitch leadless package (DFN) with the standard dual op amp pinout. The LT1802 features the standard quad op amp configuration and is available in the 14-pin plastic SO package. The LT1801/LT1802 can be used as plug-in replacements for many op amps to improve input/output range and performance.
