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.

    ... SBOS393D – MARCH 2007 – REVISED MAY 2009........................................................................................................................................................... This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications ...
