High Voltage, Bidirectional

Current Sense Amplifier

FeaTures

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.

Buffered Output with 3 Gain Options:

10V/V, 20V/V, 50V/V

Gain Accuracy: 0.5% Max

Input Common Mode Voltage Range: –5V to 80V

AC CMRR > 80dB at 100kHz

The LT1999 senses current via an external resistive shunt

andgeneratesanoutputvoltage,indicatingbothmagnitude

and direction of the sensed current. The output voltage is

referencedhalfwaybetweenthesupplyvoltageandground,

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 monitoring

currents in H-Bridge motor controls, switching power

supplies, solenoid currents, and battery charge currents

from full charge to depletion.

Input Offset Voltage: 1.5mV Max

–3dB Bandwidth: 2MHz

Smooth, Continuous Operation Over Entire Common

Mode Range

4kV HBM Tolerant and 1kV CDM Tolerant

Low Power Shutdown <10µA

–55°C to 150°C Operating Temperature Range
