DESCRIPTION
The voltage-output TSM9634 current-sense
amplifiers are electrically and form-factor identical to
the MAX9634 current-sense amplifiers. Consuming a
very low 1μA supply current, the TSM9634 high-side
current-sense amplifiers exhibit a 250-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
TSM9634 features a wide input common-mode
voltage range from 1.6V to 28V.
The SOT23 package makes the TSM9634 an ideal
choice for pcb-area-critical, low-current, high-
accuracy current-sense applications in all battery-
powered portable instruments.
All TSM9634s are specified for operation over the
-40°C to +85°C extended temperature range.
