DESCRIPTIO

The LTC

ential, low power amplifiers. The LTC1992 is an uncon-

strained fully differential amplifier. The LTC1992-1,

LTC1992-2, LTC1992-5 and LTC1992-10 are fixed gain

blocks (with gains of 1, 2, 5 and 10 respectively) featuring

precision on-chip resistors for accurate and ultrastable

gain. All of the LTC1992 parts have a separate internal

common mode feedback path for outstanding output

phase balancing and reduced second order harmonics.

The V

pendent of the input common mode level. This feature

makes level shifting of signals easy.

The amplifiers’ differential inputs operate with signals

ranging from rail-to-rail with a common mode level from

the negative supply up to 1.3V from the positive supply.

The differential input DC offset is typically 250µV. The rail-

to-rail outputs sink and 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-pin MSOP package.
