LT1213/LT1214 28MHz, 12V/µs, Single Supply Dual and Quad Precision Op Amps
U FEATURES DESCRIPTIO
■ Slew Rate: 12V/µs Typ The LT®1213 is a dual, single supply precision op amp with ■ Gain-Bandwidth Product: 28MHz Typ a 28MHz gain-bandwidth product and a 12V/µs slew rate. ■ Fast Settling to 0.01% The LT1214 is a quad version of the same amplifier. The 2V Step to 200µV: 500ns Typ DC precision of the LT1213/LT1214 eliminates trims in 10V Step to 1mV: 1.1µs 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: 275µV Max The LT1213/LT1214 will operate on any supply greater Input Offset Voltage Drift: 6µV/°C Max than 2.5V and less than 36V total. These amplifiers are Input Offset Current: 40nA Max specified at single 3.3V, single 5V and ±15V supplies, and Input Bias Current: 200nA Max only require 2.7mA of quiescent supply current per ampli- Open-Loop Gain: 1200V/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 Output Swings to Ground While Sinking Current loads. ■ Low Input Noise Voltage: 10nV/√Hz Typ ■
U
Low Input Noise Current: 0.2pA/√Hz Typ
APPLICATIO S
■ Specified at 3.3V, 5V and ±15V ■ ■ Large Output Drive Current: 30mA Min 2.5V Full-Scale 12-Bit Systems: VOS ≤ 0.45LSB ■ ■ Low Supply Current per Amplifier: 3.5mA Max 10V Full-Scale 16-Bit Systems: VOS ≤ 1.8LSB ■ ■ Dual in 8-Pin DIP and SO-8 Active Filters ■ ■ Quad in 14-Pin DIP and NARROW SO-16 Photodiode Amplifiers ■
