AS331KTR-G1

The AS331KTR-G1 is a single precision voltage comparator from Diodes Incorporated, featuring a typical input offset voltage of 1mV and high voltage gain. Designed for single-supply operation over a wide voltage range of 2V to 36V, it also supports dual supplies of ±1V to ±18V. The device draws a low supply current of 0.4mA typical at 5V, independent of the supply voltage magnitude. It offers an open collector output with a low saturation voltage of 200mV typical at 4mA, making it suitable for driving loads and interfacing with logic circuits. The input common mode voltage range includes ground, and the differential input voltage range equals the power supply voltage. Housed in a surface-mount SOT-23-5 package (SC-74A/SOT-753), the AS331KTR-G1 operates over a temperature range of -40°C to 85°C. Typical applications include battery chargers, cordless telephones, switching power supplies, DC-DC modules, PC motherboards, and communication equipment. The device is fully RoHS3 compliant, lead-free, and halogen and antimony free.
