LTC1992 Family
–IN, +IN (Pins 1, 8): Inverting and Noninverting Inputs
of the Amplifier. For the LTC1992 part, these pins are
connected directly to the amplifier’s P-channel MOSFET
input devices. The fixed gain LTC1992-X parts have preci-
sion, on-chip gain setting resistors. The input resistors
are nominally 30k for the LTC1992-1, LTC1992-2 and
LTC1992-5 parts. The input resistors are nominally 15k
for the LTC1992-10 part.
V
The voltage on this pin sets the output signal’s common
mode voltage level. The output common mode level is set
independent of the input common mode level. This is a
high impedance input and must be connected to a known
and controlled voltage. It must never be left floating.

should be bypassed with 0.1µF capacitors to an adequate ana-
log ground or ground plane. The bypass capacitors should
be located as closely as possible to the supply pins.
+OUT, –OUT (Pins 4, 5): The Positive and Negative
Outputs of the Amplifier. These rail-to-rail outputs are
designed to drive capacitive loads as high as 10,000pF .
V
to an on-chip resistive voltage divider to provide a mid-
supply reference. This provides a convenient way to set
the output common mode level at half-supply. If used for
this purpose, Pin 2 will be shorted to Pin 7, Pin 7 should
be bypassed with a 0.1µF capacitor to ground. If this refer-
ence voltage is not used, leave the pin floating.
