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 –16V
to +80V. The INA203, INA204, and INA205 are
available with three output voltage scales: 20V/V,
50V/V, and 100V/V, with up to 500kHz bandwidth.
The INA203, INA204, and INA205 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.
14-pin versions also provide a 1.2V reference output.
The INA203, INA204, and INA205 operate from a
single +2.7V to +18V supply. They are specified over
the extended operating temperature range of –40°C
to +125°C.
