The document describes the features and characteristics of Analog Devices' CMP04 quad low power, precision comparator, including high gain, single- or dual-supply operation, input voltage range including ground, low power consumption, low input bias current and offset current, low offset voltage, low output saturation voltage, and compatibility with various logic outputs.
The CMP04 is a quad low power precision comparator designed for single- or dual-supply operation. It features high gain (200 V/mV typical), low input bias current (100 nA max), and low offset voltage (1 mV max). The device includes ground in its input voltage range for single-supply designs and offers open-collector TTL outputs compatible with various logic families.
Key specifications include a maximum supply current of 2 mA per comparator, which is independent of supply voltage. The device directly replaces the LM139, LM239, and LM339 comparators. It is available in a 14-lead SOIC package and operates over a temperature range of -40°C to +85°C for the CMP04FS variant.
