current sense amplifier is offered with preset gains of
20, 50 and 100 V/V. The Common-mode input range
(V
IP
) is +3V to +65V. The Differential-mode input range
(V
DM
= V
IP
– V
IM
)
supports
unidirectional
and
bidirectional applications.
The power supply can be set between 2.0V and 5.5V.
Parts in the SOT-23 package are specified over -40°C
to +125°C (E-Temp), while parts in the 3×3 VDFN
package are specified over -40°C to +150°C (H-Temp).
The Zero-Drift architecture supports very low input
errors, which allow a design to use shunt resistors of
lower value (and lower power dissipation).
