Precision Quad Comparators
The HA-4900 series are monolithic, quad, precision comparators offering fast response time, low offset voltage, low offset current and virtually no channel-to-channel crosstalk for applications requiring accurate, high speed, signal level detection. These comparators can sense signals at ground level while being operated from either a single +5V supply (digital systems) or from dual supplies (analog networks) up to ±15V. The HA-4900 series contains a unique current driven output stage which can be connected to logic system supplies (VLOGIC+ and VLOGIC-) to make the output levels directly compatible (no external components needed) with any standard logic or special system logic levels. In combination analog/digital systems, the design employed in the HA-4900 series input and output stages prevents troublesome ground coupling of signals between analog and digital portions of the system. These comparators’ combination of features make them ideal components for signal detection and processing in data acquisition systems, test equipment and microprocessor/analog signal interface networks. For military grade product, refer to the HA-4902/883 data sheet.

CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
NOTES: 1. Maximum power dissipation, including output load, must be designed to maintain the junction temperature below 175oC for ceramic packages, and below 150oC for plastic packages. 2. Total Power Dissipation (T.P.D.) is the sum of individual dissipation contributions of V+, V- and VLOGIC shown in curves of Power Dissipation vs Supply Voltages (see Performance Curves). The calculated T.P.D. is then located on the graph of Maximum Allowable Package Dissipation vs Ambient Temperature to determine ambient temperature operating limits imposed by the calculated T.P.D. (See Performance Curves). For instance, the combination of +15V, -15V, +5V, 0V (V+, V-, VLOGIC+, VLOGIC-) gives a T.P.D. of 350mW, the combination +15V, -15V, +15V, 0V gives a T.P.D. of 450mW. 3. θJA is measured with the component mounted on an evaluation PC board in free air.

Minimum differential input voltage required to ensure a defined output state. 5. Input bias currents are essentially constant with differential input voltages up to ±9V. With differential input voltages from ±9V to ±15V, bias current on the more negative input can rise to approximately 500µA. This will also cause higher supply currents. 6. VCM = 0V. Input sensitivity is the worst case minimum differential input voltage required to guarantee a given output logic state. This parameter includes the effects of offset voltage and voltage gain. 7. For tPD(1); 100mV input step, -10mV overdrive. For tPD(0); -100mV input step, 10mV overdrive. Frequency ≈ 100Hz; Duty Cycle ≈ 50%; Inverting input driven. See Figure 1 for Test Circuit.

Supply Connections
This device is exceptionally versatile in working with most available power supplies. The voltage applied to the V+ and Vterminals determines the allowable input signal range; while the voltage applied to the VL+ and VL- determines the output swing. In systems where dual analog supplies are available, these would be connected to V+ and V-, while the logic supply and return would be connected to VLOGIC+ and VLOGIC -. The analog and logic supply commons can be connected together at one point in the system, since the comparator is immune to noise on the logic supply ground. A negative output swing may be obtained by connecting VL+ to ground and VL- to a negative supply. Bipolar output swings (15VP-P, Max) may be obtained using dual supplies. In systems where only a single logic supply is available (+5V to 15V), V+ and VLOGIC+ may be connected together to the positive supply while V- and VLOGIC- are grounded. If an input signal could swing negative with respect the V- terminal, a resistor should be connected in series with the input to limit input current to < 5mA since the C-B junction of the input transistor would be forward biased.
Power Supply Decoupling
Decouple all power supply lines with 0.01µF ceramic capacitors to ground line located near the package to reduce coupling between channels or from external sources.
