INTEGRATED CIRCUITS AU2901 Quad voltage comparator Product data Supersedes data of 1994 Aug 31 File under Integrated Circuits, IC11 Handbook 2001 Aug 03 Philips Semiconductors Philips Semiconductors Product data Quad voltage comparator AU2901 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.

Derate above 25 C, at the following rates: N Package at 11.4 mW/C D Package at 8.3 mW/C 2. Short circuits from the output to V+ can cause excessive heating and eventual destruction. The maximum output current is approximately 20 mA 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 -0.3 VDC. 2001 Aug 03 3 Philips Semiconductors Product data Quad voltage comparator AU2901 ELECTRICAL CHARACTERISTICS V+ = 5 VDC; -40 C Tamb 125 C, unless otherwise specified.

Positive excursions of input voltage may exceed the power supply level by 17 V. 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 -0.3 VDC (or 0.3 VDC below the magnitude of the negative power supply, if used). 2. At output switch point, VO 1.4 VDC, RS = 0 with V+ from 5 VDC to 30 VDC; and over the full input common-mode range (0 VDC to V+ - 1.5 VDC). 3. The input common-mode voltage or either input signal voltage should not be allowed to go negative by more than 0.3 V. The upper end of the common-mode voltage range is V+ - 1.5 V, but either or both inputs can go to 30 VDC 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 100 mV input step with a 5 mV overdrive. For larger overdrive signals, 300 ns can be obtained (see Typical Performance Characteristics section). 2001 Aug 03 4 Philips Semiconductors Product data Quad voltage comparator AU2901 EQUIVALENT CIRCUIT V+ 500 pF 700 k 30 k 5.1 k 3.0 k V+ 100 k + VC FREQUENCY CONTROL VOLTAGE INPUT 50 k - 10 - + 0.01 F V - /2 1/4AU2901 OUTPUT 1 0.1 F 20 k 20 k V + /2 + OUTPUT 2 + - NOTES: V+ = 30 VDC + 250 m VDC < VC 50 VDC 700 H < fO = 100 kHz Two-Decade High-Frequency VCO + V (12 V DC) +V 2RS REF HI RS 10K + - LAMP +V +5V IN + DC 360 2RS +VREF LOW 2N2222 - Limit Comparator + +V REF 4 100 - 100 k +5V 360 DC 5 VDC + - +VREF 1.4 VDC VO 10 k o -12 V + +V VO REF 3 - 100 100 k +5V 360 DC -12 VDC TTL-to-MOS Logic Converter V+ 200 k 2.0 k V+ 0.1 F + - VO 0 +V + REF 2 - 100 k +5V 360 DC 100 k 100 +V + REF 1 - 100 100 k 200 k CRYSTAL 1 - 100 kHz Visible Voltage Indicator Crystal-Controlled Oscillator NOTE: Input of unused comparators should be grounded.
