External resistors, selected by the designer, determine gain, gain accuracy and gain drift, and using precision resistors enables gain accuracy better than 99%. The topology of the LTC6102 allows the designer to customize power consumption, response time and the input/output impedance characteristics for the application. Furthermore, the LTC6102 has a 1us response time, allowing it to initiate fault protection or power shutdown in the event of unexpected load or supply current surges.
The LTC6102 breaks new ground by applying LTC’s zero-drift technology to high side current sensing” says Mike Kultgen, design manager for Linear Technology. As a result, the LTC6102 will enable significantly more accurate current measurements and control applications.
Two versions provide the choice of common mode voltage: the LTC6102 operates with inputs up to 70V, and the LTC6102HV operates with inputs up to 105V. Both versions are in full production, with prices starting at $1.72 each in 1,000-piece quantities.
