DESCRIPTION
The LTC®1992 product family consists of five fully differen-
tial, low power amplifiers. The LTC1992 is an unconstrained
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 VOCM pin sets
the output common mode level independent 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.
