DescripTion
The
LT
®
1999
is a high speed precision current sense am-
plifier, designed to monitor bidirectional currents over a
wide common mode range. The LT1999 is offered in three
gain options: 10V/V, 20V/V, and 50V/V.
The LT1999 senses current via an external resistive shunt
and generates an output voltage, indicating both magnitude
and direction of the sensed current. The output voltage is
referenced halfway between the supply voltage and ground,
or an external voltage can be used to set the reference
level. With a 2MHz bandwidth and a common mode input
range of –5V to 80V, the LT1999 is suitable for monitor-
ing currents in H-Bridge motor controls, switching power
supplies, solenoid currents, and battery charge currents
from full charge to depletion.
The LT1999 operates from an independent 5V supply
and draws 1.55mA. A shutdown mode is provided for
minimizing power consumption.
The LT1999 is available in an 8-lead SOP, an 8-lead MSOP
(original pinout), or an 8-lead pinout option engineered
for FMEA.
