LT1215/LT1216 23MHz, 50V/µs, Single Supply Dual and Quad Precision Op Amps
U FEATURES DESCRIPTIO
■ Slew Rate: 50V/µs Typ The LT®1215 is a dual, single supply precision op amp with ■ Gain-Bandwidth Product: 23MHz Typ a 23MHz gain-bandwidth product and a 50V/µs slew rate. ■ Fast Settling to 0.01% The LT1216 is a quad version of the same amplifier. The 2V Step to 200µV: 250ns Typ DC precision of the LT1215/LT1216 eliminates trims in 10V Step to 1mV: 480ns Typ most systems while providing high frequency perfor- ■ Excellent DC Precision in All Packages mance not usually found in single supply amplifiers. Input Offset Voltage: 450µV Max The LT1215/LT1216 will operate on any supply greater Input Offset Voltage Drift: 10µV/°C Max than 2.5V and less than 36V total. These amplifiers are Input Offset Current: 120nA Max specified on single 3.3V, single 5V and ±15V supplies, and Input Bias Current: 600nA Max only require 5mA of quiescent supply current per ampli- Open-Loop Gain: 1000V/mV Min fier. The inputs can be driven beyond the supplies without ■ Single Supply Operation damage or phase reversal of the output. The minimum Input Voltage Range Includes Ground output drive is 30mA, ideal for driving low impedance loads. Output Swings to Ground While Sinking Current
