3 Description
The INA203, INA204, and INA205 are a family of
unidirectional current-shunt monitors with voltage
output, dual comparators, and voltage reference. The
INA203, INA204, and INA205 can sense drops
across shunts at common-mode voltages from –16 V
to 80 V. The INA203, INA204, and INA205 are
available with three output voltage scales: 20 V/V, 50
V/V, and 100 V/V, with up to 500-kHz bandwidth.
The INA203, INA204, and INA205 also incorporate
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. 14-pin
versions also provide a 1.2-V reference output.
The INA203, INA204, and INA205 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.
