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.
