LT1801/LT1802 Dual/Quad 80MHz, 25V/s Low Power Rail-to-Rail Input and Output Precision Op Amps FEATURES DESCRIPTION n Gain Bandwidth Product: 80MHz The LT 1801/LT1802 are dual/quad, low power, high speed n Input Common Mode Range Includes Both Rails rail-to-rail input and output operational ampli ers with n Output Swings Rail-to-Rail excellent DC performance. The LT1801/LT1802 feature n Low Voltage Operation: Single or Split Supplies reduced supply current, lower input offset voltage, lower 2.3V to 12.6V input bias current and higher DC gain than other devices n Low Quiescent Current: 2mA/Ampli er Max with comparable bandwidth. n Input Offset Voltage: 350V Max Typically, the LT1801/LT1802 have an input offset voltage n Input Bias Current: 250nA Max of less than 100V, an input bias current of less than 50nA n 3mm 3mm 0.8mm DFN Package and an open-loop gain of 85 thousand. n Large Output Current: 50mA Typ n The LT1801/LT1802 have an input range that includes Low Voltage Noise: 8.5nV/Hz Typ n both supply rails and an output that swings within 20mV Slew Rate: 25V/s Typ n of either supply rail to maximize the signal dynamic range Common Mode Rejection: 105dB Typ n in low supply applications. Power Supply Rejection: 97dB Typ n Open-Loop Gain: 85V/mV Typ The LT1801/LT1802 maintain their performance for sup- n Operating Temperature Range: 40C to 85C plies from 2.3V to 12.6V and are speci ed at 3V, 5V and n LT1801 is Available in 8-Lead SO, MS8 and DFN 5V supplies. The inputs can be driven beyond the supplies Packages without damage or phase reversal of the output. n LT1802 is Available in 14-Lead SO Package The LT1801 is available in the MS8, SO-8 and the 3mm 3mm 0.8mm dual ne pitch leadless package (DFN) APPLICATIONS with the standard dual op amp pinout. The LT1802 features n Low Voltage, High Frequency Signal Processing the standard quad op amp con guration and is available n Driving A/D Converters in the 14-pin plastic SO package. The LT1801/LT1802 can n Rail-to-Rail Buffer Ampli ers be used as plug-in replacements for many op amps to n Active Filters improve input/output range and performance. n Video Line Driver For a single version of these ampli ers, see the LT1800 L, LT, LTC and LTM are registered trademarks of Linear Technology Corporation.
