The LTC?1992 product family includes five fully differential, low power amplifiers. The LTC1992 is an unconstrained fully differential amplifier. The LTC1992-1, LTC1992-2, LTC1992-5 and LTC1992-10 are fixed gain parts (gains of 1, 2, 5 and 10, respectively) with precision on-chip resistors designed for accurate and ultra-stable gain. The LTC1992 devices each feature a separate internal common-mode feedback path for superior output phase balance and reduction of second-order harmonics. The VOCM pin sets the output common-mode level independent of the input common-mode level. This feature makes level shifting of signals simple and easy.

The differential inputs of these amplifiers operate with a rail-to-rail signal range and a common-mode level range from the negative supply to 1.3V from the positive supply. The differential input DC offset is typically 250µV. Rail-to-rail outputs sink or source 10mA. The LTC1992 is stable for all capacitive loads up to 10,000pF.

The LTC1992 can be used in single-supply applications with supply voltages as low as 2.7V. It can also be used with dual supplies up to ±5V. The LTC1992 is available in an 8-lead MSOP package.
