DESCRIPTIO
The LT
®
1990 is a micropower precision difference ampli-
fier with a very high common mode input voltage range. It
has pin selectable gains of 1 or 10. The LT1990 operates
over a
±250V
common mode voltage range on a
±15V
supply. The inputs are fault protected from common
mode voltage transients up to
±350V
and differential
voltages up to
±500V.
The LT1990 is ideally suited for both
high side and low side current or voltage monitoring.
On a single 5V supply, the LT1990 has an adjustable 85V
input range, 70dB min CMRR and draws less than 120µA
supply current. The rail-to-rail output maximizes the dy-
namic range, especially important for single supplies as
low as 2.7V.
The LT1990 is specified for single 3V, 5V and
±15V
supplies over both commercial and industrial temperature
ranges. The LT1990 is available in the 8-pin SO package.
