APPLICATIONS

DESCRIPTION

The INA206, INA207, and INA208 are a family of

high-side, current-shunt monitors with voltage output, dual

comparators, and voltage reference. The INA206,

INA207, and INA208 can sense drops across shunts at

common-mode voltages from −16V to +80V. The INA206,

INA207, and INA208 are available with three output

voltage scales: 20V/V, 50V/V, and 100V/V, with up to

500kHz bandwidth.

The INA206, INA207, and INA208 also incorporate two

open-drain comparators with internal 0.6V references. On

14-pin versions, the comparator references can be

overridden by external inputs. Comparator 1 includes a

latching

capability,

and

Comparator

2

has

a

user-programmable delay on 14-pin versions. 14-pin

versions also provide a 1.2V reference output.

The INA206, INA207, and INA208 operate from a single

+2.7V to +18V supply. They are specified over the

extended operating temperature range of −40

°C to

+125

°C.
