Product Summary
The lt121s5-105 is a dual, single supply precision op amp with a 14MHz gain-bandwidth product and a 7V/ms slew rate. The LT1212 is a quad version of the same amplifier. The DC precision of the lt121s5-105 eliminates trims in most systems while providing high frequency performance not usually found in single supply amplifiers. The lt121s5-105 will operate on any supply greater than 2.5V and less than 36V total. These amplifiers are specified on single 3.3V, single 5V and ±5V supplies, and only require 1.3mA of quiescent supply current per amplifier. The inputs can be driven beyond the supplies without damage or phase reversal of the output. The minimum output drive is 20mA, ideal for driving low impedance loads. The lt121s5-105 applications are: (1)2.5V Full Scale 12 Bit Systems: VOS ≦ 0.45LSB; (2)10V Full Scale 16 Bit Systems: VOS ≦ 1.8LSB; (3)Active Filters; (4)Photo Diode Amplifiers; (5)DAC Current to Voltage Amplifiers; (6)Battery Powered Systems.
