DESCRIPTION
The voltage-output TS1102 current-sense amplifiers
are form-factor identical and electrical improvements
to the MAX9938 and the MAX9634 current-sense
amplifiers. The TS1102 is the latest addition to the
TS1100
family
of
current-sense
amplifiers.
Consuming a very low 1μA supply current, the
TS1102 high-side current-sense amplifiers combine a
200-µV (max) V
OS
and a 0.5% (max) gain error for
cost-sensitive applications. For all high-side current-
sensing applications, the TS1102 features a wide
input common-mode voltage range from 2V to 25V.
The SOT23 package makes the TS1102 an ideal
choice for pcb-area-critical, low-current, high-
accuracy current-sense applications in all battery-
powered, remote or hand-held portable instruments.
All TS1102s are specified for operation over the
-40°C to +105°C extended temperature range.
