DESCRIPTION
The
LT
®
1999
is a high speed precision current sense
amplifier, 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 mag-
nitude 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 com-
mon mode input range of –5V to 80V, the LT1999 is suit-
able for monitoring 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 mini-
mizing 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.
