The RTQ6060-QA series comprises high-precision current monitors commonly used in current-reporting systems and current-sensing circuits for precision current measurement and system optimization. These devices can sense a low voltage drop (10mV) across the shunt resistor at common-mode voltages ranging from -0.3V to 36V. They feature extremely low input offset, offset drift, gain error, and gain drift, all achieved through a zero-drift architecture. Six fixed gains options - 50, 75, 100, 200, 500, and 1000V/V - are available to accommodate different current scaling applications.These devices operate from a single power supply ranging from 2.7V to 36V and draw a maximum supply current of 100μA. The RTQ6060-QA is available in an SC-70-6 package.The recommended ambient temperature range is -40°C to 125°C.
