ADCMP391

Data Sheet Single/Dual/Quad Comparators With Known Power-Up State ADCMP391/ADCMP392/ADCMP393 FEATURES Single-supply voltage operation: 2.3 V to 5.5 V Rail-to-rail common-mode input voltage range Low input offset voltage across VCMR: 1 mV typical Guarantees comparator output logic low from VCC = 0.9 V to undervoltage lockout (UVLO) Operating temperature range: −40°C to +125°C Package types: 8-lead, narrow body SOIC (ADCMP391/ADCMP392) 14-lead, narrow body SOIC (ADCMP393) 14-lead TSSOP (ADCMP393) APPLICATIONS Battery management/monitoring Power supply detection Window comparators Threshold detectors/discriminators Microprocessor systems GENERAL DESCRIPTION The ADCMP391/ADCMP392/ADCMP393 are single/dual/quad rail-to-rail input, low power comparators ideal for use in general-purpose applications. These comparators operate from a single supply voltage of 2.3 V to 5.5 V and draw a minimal amount of current. The single ADCMP391 consumes only 18.6 µA of supply current. The dual ADCMP392...
