CM339 is a low power quad voltage comparator produced by Champion Microelectronic Corporation. It has a maximum offset voltage of ±2mV and can be powered by a single power supply with a voltage range of +2V to +36V or by split power supplies with a voltage range of ±1V to ±18V.
The Champion CM339 is a device consisting of four independent precision voltage comparators designed to operate from a single power supply over a wide range of voltages or split supplies. It features an input common mode voltage range that includes ground, even when operated from a single supply.
Key characteristics include very low supply current (1.1mA), low input bias and offset currents/voltages, and TTL/DTL/ECL/MOS/CMOS compatible outputs. The device is available in 14-pin PDIP and SOP packages.
