DESCRIPTION
The INA200, INA201, and INA202 are high-side
current-shunt
INA200−INA202 can sense drops across shunts at
common-mode voltages from −16V to 80V. The
INA200−INA202 are available with three output voltage
scales: 20V/V, 50V/V, and 100V/V, with up to 500kHz
bandwidth.
The INA200, INA201, and INA202 also incorporate an
open-drain comparator and internal reference providing a
0.6V threshold. External dividers are used to set the
current trip point. The comparator includes a latching
capability, which can be made transparent by grounding
(or leaving open) the RESET pin.
The INA200, INA201, and INA202 operate from a single
+2.7V to +18V supply, drawing a maximum of 1800µA of
supply current. Package options include the very small
MSOP-8 and the SO-8. All versions are specified over the
extended operating temperature range of −40°C to
+125°C.
