3 Description

The INA206, INA207, and INA208 are a family of

undirectional current-shunt monitors with voltage output, dual comparators, and voltage reference. The

INA206, INA207, and INA208 can sense drops

across shunts at a common-mode voltages from –16

V to 80 V. The INA206, INA207, and INA208 are available with three output voltage scales: 20 V/V, 50

V/V, and 100 V/V, with up to 500-kHz bandwidth.

The INA206, INA207, and INA208 also incorporates

two open-drain comparators with internal 0.6-V

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. The 14-pin versions also provide a 1.2 V

reference output.

The INA206, INA207, and INA208 operate from a

single 2.7-V to 18-V supply. They are specified over

the extended operating temperature range of –40°C

to 125°C.
