TSM9634

www.DataSheet.co.kr TSM9634 A 1µA, SOT23 Precision Current-Sense Amplifier FEATURES ♦ Alternate-source for MAX9634 ♦ Ultra-Low Supply Current: 1μA ♦ Wide Input Common Mode Range: +1.6V to +28V ♦ Low Input Offset Voltage: 250µV (max) ♦ Low Gain Error: <0.5% (max) ♦ Voltage Output ♦ Four Gain Options Available: TSM9634T: Gain = 25V/V TSM9634F: Gain = 50V/V TSM9634H: Gain = 100V/V TSM9634W: Gain = 200V/V ♦ 5-Pin SOT23 Packaging 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, 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.
