DESCRIPTION

LTC2991

I2C Temperature, Voltage

and Current Monitor

Demonstration circuit 1785A features the LTC®2991, a high

performance temperature, voltage and current monitor

that uses an I2C interface for communication. It offers

sub-millivolt voltage resolution, 1% current measurement

and 1°C temperature accuracy.

DC1785A is a member of Linear Technology‘s QuikEval™

family of demonstration boards. It is designed to allow easy

evaluation of the LTC2991 and may be connected directly

to the target application’s analog signals while using the

DC590 USB Serial Controller board and supplied software

to measure performance. The exposed ground planes allow

proper grounding to prototype circuitry. After evaluating

with Linear Technology’s software, the digital signals can

be connected to the end application’s processor/controller

for development of the serial interface.
