MAX34406

www.DataSheet.co.kr 19-5930; Rev 1; 1/12 EVALUATION KIT AVAILABLE MAX34406 Quad Current-Sense Amplifier with Overcurrent Threshold Comparators General Description The MAX34406 is a quad, high-side, unidirectional, current-sense amplifier that offers precision accuracy. It provides analog outputs for each of the four amplifiers that can be routed to an external ADC, and contains four overcurrent comparators with a fixed 1.0V threshold. All four comparators are logically ORed, and the result can be delayed/filtered with an external capacitor before it is fed to a latched common shutdown open-drain output pin. Features S Four Precision Current-Sense Amplifiers S Fixed Gains of 25V/V, 50V/V, 100V/V, and 200V/V S Less Than ±600µV of Input Offset S Less Than ±0.6% of Gain Error (T/F/H) or ±0.8% of Gain Error (W) S Wide 2.0V to 28V Common Mode Range S Analog Voltage Outputs for Each Amplifier S Independent Overcurrent Comparators with Fixed 1.0V Threshold S Low Power Consumption S -40NC to +85NC Temperature Range S Small 24-Pin TQFN (4mm x 4mm) Package Ordering Information appears at end of data sheet.
