GENERAL DESCRIPTION
TYPICAL INTERFACE
5.0
Four precision independent comparators comprise the CMP04. Performance highlights include a very low offset voltage, low output saturation voltage, and high gain in a single-supply design. The input voltage range includes ground for singlesupply operation and V- for split supplies. A low power supply current of 2 mA, which is independent of supply voltage, makes this the preferred comparator for precision applications requiring minimal power consumption. Maximum logic interface flexibility is offered by the open-collector TTL output.

NOTES 1 Absolute maximum ratings apply to both DICE and packaged parts, unless otherwise noted. Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those listed in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. 2 JA is specified for worst-case mounting conditions, i.e., JA is specified for device soldered to printed circuit board for SOIC package.
ORDERING GUIDE
Model CMP04FS
TA = 25 C VOS 1 mV
Temperature Ranges -40C to +85C
Package Descriptions 14-Lead SOIC
Package Options R-14
CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the CMP04 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality.
