TS1101 A 1A, +2V to +27V Bidirectional Precision Current-Sense Amplifier FEATURES DESCRIPTION The bi-directional, voltage-output TS1101 current- Ultra-Low Supply Current: 1A Wide Input Common Mode Range: +2V to +27V sense amplifiers are the lowest-power and most accurate current-sense amplifiers available today. Low Input Offset Voltage: 100V (max) Low Gain Error: 0.6% (max) Consuming a very low 1A supply current, the Voltage Output TS1101 high-side current-sense amplifiers exhibit a 100-V (max) VOS and a 0.6% (max) gain error, both SIGN Comparator Output: No Dead Zone at ILOAD Switchover specifications optimized for any precision current measurement. For all high-side bidirectional current- Four Gain Options Available: sensing applications, the TS1101s are self-powered TS1101-25: Gain = 25V/V TS1101-50: Gain = 50V/V and feature a wide input common-mode voltage TS1101-100: Gain = 100V/V range from 2V to 27V. A SIGN comparator digital output is also provided that indicates the direction of TS1101-200: Gain = 200V/V 6-Lead SOT23 Packaging current flow depending on the external connections to the TS1101s RS+ and RS- input terminals. APPLICATIONS The SOT23 package makes the TS1101 an ideal Notebook Computers choice for pcb-area-critical, supply-current-conscious, Power Management Systems high-accuracy current-sense applications in all Portable/Battery-Powered Systems battery-powered and portable instruments. Smart Chargers Smart Phones All TS1101s are specified for operation over the -40C to +105C extended temperature range.
