The CSA315 is a unidirectional current shunt monitor amplifier with features including analog voltage output, dual comparators, and an integrated voltage reference. The CSA315 can detect the voltage across a shunt resistor over a common-mode voltage range from -6V to 80V. The CSA315L, CSA315M, and CSA315P correspond to three different gain options: 20V/V, 50V/V, and 100V/V, with a typical bandwidth of 420kHz.The CSA315 also integrates two open-drain comparators with an internal 0.6V reference voltage. The internal reference of the comparators can be overridden by an external input. Comparator 1 features a latch function, while the delay of Comparator 2 can be programmed using an external capacitor. Additionally, a 1.2V reference voltage output is provided.The CSA315 operates from a supply voltage range of 2.7V to 5.5V and is specified to work over a temperature range of -40°C to 125°C.
