DESCRIPTION
The voltage-output TS1100 current-sense amplifiers
are form-factor identical and electrical improvements
to the MAX9938 and the MAX9634 current-sense
amplifiers. Consuming a very low 1μA supply current,
the TS1100 high-side current-sense amplifiers exhibit
a 100-µV (max) VOS and a 0.5% (max) gain error,
both specifications optimized for any precision current
measurement. For all high-side current-sensing
applications, the TS1100 features a wide input
common-mode voltage range from 2V to 25V.
The SOT23 package makes the TS1100 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 TS1100s are specified for operation over the
-40°C to +105°C extended temperature range.
