TSM9634 A 1A, SOT23 Precision Current-Sense Amplifier FEATURES DESCRIPTION Alternate-source for MAX9634 The voltage-output TSM9634 current-sense Ultra-Low Supply Current: 1A amplifiers are electrically and form-factor identical to Wide Input Common Mode Range: +1.6V to +28V the MAX9634 current-sense amplifiers. Consuming a Low Input Offset Voltage: 250V (max) very low 1A supply current, theTS M9634 high-side Low Gain Error: <0.5% (max) current-sense amplifiers exhibit a 250-V (max) V OS Voltage Output and a 0.5% (max) gain error, both specifications Four Gain Options Available: optimized for any precision current measurement. For TSM9634T: Gain = 25V/V all high-side current-sensing applications, the TSM9634F: Gain = 50V/V TSM9634 features a wide input common-mode TSM9634H: Gain = 100V/V voltage range from 1.6V to 28V. TSM9634W: Gain = 200V/V 5-Pin SOT23 Packaging The SOT23 package makes the TSM9634 an ideal choice for pcb-area-critical, low-current, high- accuracy current-sense applications in all battery- APPLICATIONS powered portable instruments. Notebook Computers Power Management Systems All TSM9634s are specified for operation over the Portable/Battery-Powered Systems -40C to +85C extended temperature range.
