TSM9634 : +1.6V TO +28V, 1µA Precision Current-Sense Amplifiers

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, highaccuracy current-sense applications in all batterypowered portable instruments.

All TSM9634s are specified for operation over the
-40°C to +85°C extended temperature range.
