The LT1996 is a precision operational amplifier with gain selection function. It integrates eight precision resistors, a single chip can achieve accurate voltage amplification. Gain range is -117 to 118, gain accuracy is 0.05%, no external components are required. The device is particularly suitable for use as a differential amplifier, where the excellent resistor matching results in a common mode rejection ratio of greater than 80dB. The amplifier features a maximum 50µV 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; temperature variation is 0.05%.
The LT1996 combines a precision op‑amp with eight internal resistors to provide a fully integrated, gain‑selectable difference amplifier. It offers selectable gains of 9, 27 and 81 (or 1‑117 in steps) with a gain accuracy of 0.05 % and a common‑mode rejection ratio greater than 80 dB.
The device operates from a wide supply range of 2.7 V to 36 V, draws only 100 µA supply current, and delivers rail‑to‑rail output within 40 mV of either rail. Its internal resistors are matched to 0.05 % over temperature, and the op‑amp provides a gain‑bandwidth product of about 560 kHz.
