Quad voltage comparator
Product specification
AU2901
DESCRIPTION
The AU2901 consists of four independent precision voltage
comparators, with an offset voltage specification as low as 2.0mV
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 2.0VDC to 36VDC or dual
supplies ±1.0VDC to ±18VDC
Very low supply current drain (0.8mA) independent of supply
voltage (1.0mW/comparator at 5.0VDC)
Low input biasing current 25nA
Low input offset current ±5nA and offset voltage
Input common–mode voltage range includes ground
Differential input voltage range equal to the power supply voltage
Low output 250mV at 4mA saturation voltage
Output voltage compatible with TTL, DTL, ECL, MOS and CMOS
logic systems

1. Derate above 25°C, at the following rates:
N Package at 11.4mW/°C
D Package at 8.3mW/°C
2. Short circuits from the output to V+ can cause excessive heating and eventual destruction. The maximum output current is approximately
20mA independent of the magnitude of V+.
3. This input current will only exist when the voltage at any of the input leads is driven negative. It is due to the collector–base junction of the
input PNP transistors becoming forward biased and thereby acting as input diode clamps. In addition to this diode action, there is also lateral
NPN parasitic transistor action on the IC chip. This transistor action can cause the output voltages of the comparators to go to the V+ voltage
level (or to ground for a large overdrive) for the time duration that an input is driven negative. This is not destructive and normal output states
will reestablish when the input voltage, which was negative, again returns to a value greater than –0.3VDC.

NOTES:
1. Positive excursions of input voltage may exceed the power supply level by 17V. As long as the other voltage remains within the
common–mode range, the comparator will provide a proper output state. The low input voltage state must not be less than –0.3VDC (or
0.3VDC below the magnitude of the negative power supply, if used).
2. At output switch point, VO 1.4VDC, RS=0with V+ from 5VDC to 30VDC; and over the full input common–mode range (0VDC to
V+ – 1.5VDC).
3. The input common–mode voltage or 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 V+ – 1.5V, but either or both inputs can go to 30VDC without damage.
4. The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant, independent of the state of
the output so no loading change exists on the reference or input lines.
5. The response time specified is for a 100mV input step with a 5mV overdrive. For larger overdrive signals, 300ns can be obtained (see
Typical Performance Characteristics section).
