Pin Configurable as a Difference Amplifier, Inverting and Noninverting Amplifier Difference Amplifier Gain Range 9 to 117 CMRR >80dB Noninverting Amplifier Gain Range 0.008 to 118 Inverting Amplifier Gain Range –0.08 to –117 Gain Error: <0.05% Gain Drift: < 3ppm/°C Wide Supply Range: Single 2.7V to Split ±18V Micropower Operation: 100µA Supply Input Offset Voltage: 50µV (Max) Gain Bandwidth Product: 560kHz Rail-to-Rail Output Space Saving 10-Lead MSOP and DFN Packages
The LT®1996 combines a precision operational amplifier with eight precision resistors to form a one-chip solution for accurately amplifying voltages. Gains from –117 to 118 with a gain accuracy of 0.05% can be achieved without any external components. The device is particularly well suited for use as a difference amplifier, where the excellent resistor matching results in a common mode rejection ratio of greater than 80dB. The amplifier features a 50µV maximum input offset voltage and a gain bandwidth product of 560kHz. The device operates from any supply voltage from 2.7V to 36V and draws only 100µA supply current on a 5V supply. The output swings to within 40mV of either supply rail. The internal resistors have excellent matching characteristics; variation is 0.05% over temperature with a guaranteed matching temperature coefficent of less than 3ppm/°C. The resistors are also extremely stable ...
