LT1800 80MHz, 25V/s Low Power Rail-to-Rail Input and Output Precision Op Amp FEATURES DESCRIPTION n The LT 1800 is a low power, high speed rail-to-rail input and Gain Bandwidth Product: 80MHz n output operational ampli er with excellent DC performance. Input Common Mode Range Includes Both Rails n The LT1800 features reduced supply current, lower input Output Swings Rail-to-Rail n offset voltage, lower input bias current and higher DC gain Low Quiescent Current: 2mA Max n than other devices with comparable bandwidth. Input Offset Voltage: 350V Max n Input Bias Current: 250nA Max The LT1800 has an input range that includes both supply n Low Voltage Noise: 8.5nV/Hz rails and an output that swings within 20mV of either n Slew Rate: 25V/s supply rail to maximize the signal dynamic range in low n Common Mode Rejection: 105dB supply applications. n Power Supply Rejection: 97dB The LT1800 maintains its performance for supplies from n Open-Loop Gain: 85V/mV 2.3V to 12.6V and is speci ed at 3V, 5V and 5V supplies. n Operating Temperature Range: 40C to 85C The inputs can be driven beyond the supplies without n Available in the 8-Pin SO and 5-Pin Low Pro le damage or phase reversal of the output. (1mm) ThinSOT Packages The LT1800 is available in the 8-pin SO package with the standard op amp pinout and in the 5-pin TSOT-23 APPLICATIONS package. For dual and quad versions of the LT1800, see n Low Voltage, High Frequency Signal Processing the LT1801/LT1802 data sheet. The LT1800 can be used n Driving A/D Converters as a plug-in replacement for many op amps to improve n Rail-to-Rail Buffer Ampli ers input/output range and performance. n Active Filters L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear n Technology Corporation.
