2 / 10 page Philips Semiconductors Product data AU2901 Quad voltage comparator 2 2001 Aug 03 853-1637 26837 DESCRIPTION The AU2901 consists of four independent precision voltage comparators, with an offset voltage specification as low as 2.0 mV max for each comparator, which were designed specifically to operate from a single power supply over a wide range of voltages. 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. These comparators also have a unique characteristic in that the input common-mode voltage range includes ground, even though they are operated from a single power supply voltage. The AU2901 was designed to directly interface with TTL and CMOS. When operated from both plus and minus power supplies, the AU2901 will directly interface with MOS logic where their low power drain is a distinct advantage over standard comparators. FEATURES • Wide single supply voltage range 2.0 V DC to 36 VDC or dual supplies ±1.0 VDC to ±18 VDC • Very low supply current drain (0.8 mA) independent of supply voltage (1.0 mW/comparator at 5.0 VDC) • Low input biasing current 25 nA • Low input offset current ±5 nA and offset voltage • Input common-mode voltage range includes ground • Differential input voltage range equal to the power supply voltage • Low output 250 mV at 4 mA saturation voltage • Output voltage compatible with TTL, DTL, ECL, MOS and CMOS logic systems APPLICATIONS • A/D converters • Wide range VCO • MOS clock generator • High voltage logic gate • Multivibrators PIN CONFIGURATION 1 2 3 4 5 6 78 14 13 12 11 10 9 OUTPUT 2 OUTPUT 1 V+ INPUT 1 – INPUT 1 + OUTPUT 3 TOP VIEW D, N Packages INPUT 1 – INPUT 1 + OUTPUT 4 GND INPUT 4 – INPUT 3 + INPUT 3 – INPUT 4 + 1 23 4 SL00106 Figure 1.
