Data sheet Advanced Analog Circuits LOW POWER LOW OFFSET VOLTAGE DUAL COMPARATORS General Description Features The AZ393 series consists of two independent precision voltage comparators with an offset voltage specification as low as 1mV. The input common mode voltage range of these comparators includes ground, even when operated from a single power supply voltage. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage. · · · · · · The AZ393 series is designed to directly interface with TTL and CMOS. · The AZ393 series can be widely used in such applications as battery charger, cordless telephone, switching power supply, DC-DC module and PC motherboard. · · AZ393 Wide supply - Voltage range: 2.0V to 18V - Single or dual supplies: ±1.0V to ± 9V Very low supply current drain: 0.4mA - independent of supply voltage Low input bias current: 25nA Low input offset current: ±5nA Low input offset voltage: 1mV Input common mode voltage range that includes ground Differential input voltage range equal to the power supply voltage Low output saturation voltage: 250mV at 4mA Open-collector output Applications · · · · · · Battery Charger Cordless Telephone Switching Power Supply DC-DC Module PC Motherboard Communication Equipment DIP-8 SOIC-8 Figure 1.

Parameter Conditions Min Typ Max Unit Input Offset Voltage (Note 2) 1.0 5.0 mV Input Bias Current I IN (+) or I IN (-) with output in linear range, VCM = 0V, (Note 3) 25 250 nA Input Offset Current I IN (+) - I IN (-), VCM = 0V 5.0 50 nA Input Common Mode Voltage Range VCC=15V, (Note 4) VCC-1.5 V Supply Current RL=∞, VCC = 5V 0.4 1.0 mA RL=∞, VCC = 18V 1.0 2.5 Voltage Gain RL ≥ 15KΩ, VCC = 8V, VO = 1V to 6V Large Signal Response Time 0 50 200 V/mV VIN = TTL logic swing, VREF = 1.4V, VRL = 5V, RL = 5.1KΩ 300 ns Response Time VRL = 5V, RL = 5.1KΩ, (Note 5) 1.3 µs Output Sink Current VIN (-) = 1V, VIN (+) = 0, VO ≤ 1.5V 16 mA Saturation Voltage VIN (-) = 1V, VIN (+) = 0, ISINK ≤ 4mA 250 Output Leakage Current VIN (-) = 0, VIN (+) = 1V, VO = 5V 0.1 6.0 400 mV nA Note 2: At output switch point, VO=1.4V, RS=0 with VCC from 5V to 15V, and over the full common-mode range (0V to VCC - 1.5V), at 25oC. Note 3: The direction of the input current is out of the PNP input stage. This current is essentially constant, independent of the state of the output, so no loading charge exists on the reference of input lines. Note 4: The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3V. The upper end of the common-mode voltage range is VCC - 1.5V, but either or both inputs can go to +18V without damage, independent of the magnitude of VCC. Note 5: The response time specified is a 100mV input step with 5mV overdrive. For large overdrive signals 300ns can be obtained.
