LM2903H LOW POWER DUAL VOLTAGE COMPARATORS ■ WIDE SINGLE SUPPLY VOLTAGE RANGE OR DUAL SUPPLIES +2V TO +36V OR ±1V TO ±18V ■ VERY LOW SUPPLY CURRENT (0.4mA) INDEPENDENT OF SUPPLY VOLTAGE (1mW/comparator at +5V) ■ LOW INPUT BIAS CURRENT: 25nA TYP ■ LOW INPUT OFFSET CURRENT: ±5nA TYP D SO-8 (Plastic Micropackage) ■ INPUT COMMON-MODE VOLTAGE RANGE INCLUDES GROUND ■ LOW OUTPUT SATURATION VOLTAGE: 250mV TYP. (IO = 4mA) ■ DIFFERENTIAL INPUT VOLTAGE RANGE EQUAL TO THE SUPPLY VOLTAGE ■ TTL, DTL, ECL, MOS, CMOS COMPATIBLE OUTPUTS DESCRIPTION This device consists of two independent low power voltage comparators designed specifically to operate from a single supply over a wide range of voltages. Operation from split power supplies is also possible. These comparators also have a unique characteristic in that the input common-mode voltage range includes ground even though operated from a single power supply voltage.

At output switch point, VO ≈ 1.4V, RS = 0Ω with VCC+ from 5V to 30V, and over the full input common-mode range (0V to VCC+ –1.5V). 2. 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 charge exists on the reference of input lines 3. 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 +30V without damage. 4. Positive excursions of input voltage may exceed the power supply level. 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 –0.3V (or 0.3V below the negative power supply, if used) 5. The response time specified is for a 100mV input step with 5mV overdrive. 6. Maximum values are guaranteed by design & evaluation. 3/5 LM2903H T AMB = - 40 °C T AMB = + 25 °C 0.6 0.4 T AMB = + 125 °C 0.2 0.0 T AM B = + 150 °C 0 10 20 30 40 SUPPLY VOLTAGE (V) INPUT VOLTAGE (mV) SUPPLY CURRENT (mA) 1.0 0.8 RESPONSE TIME FOR VARIOUS INPUT OVERDRIVES - NEGATIVE TRANSITION OUTPUT VOLTAGE (V) SUPPLY CURRENT versus SUPPLY VOLTAGE 6 5 4 3 2 1 0 0 -50 -100 Input overdrive : 5mV 5V 5.1kW 20mV eI eo 100mV Tamb= +25°C 0 0.5 1 1.5 TIME (m s) 2 INPUT CURRENT versus SUPPLY VOLTAGE RESPONSE TIME FOR VARIOUS INPUT OVERDRIVES - POSITIVE TRANSITION OUTPUT VOLTAGE (V) 40 T AMB = - 40 °C 30 20 T AMB = + 25 °C T AMB = + 150 °C 10 T AMB = + 125 °C 0 0 10 20 30 40 SUPPLY VOLTAGE (V) OUTPUT SATURATION VOLTAGE versus OUTPUT CURRENT (Vcc=5V) OUTPUT SATURATION VOLTAGE (V) 10 1 T AMB = + 150 °C T AMB = + 125 °C 0.1 TAMB = + 25 °C T AMB = - 40 °C 0.01 0.1 1 10 OUTPUT SINK CURRENT (mA) 4/5 100 INPUT VOLTAGE (mV) INPUT BIAS CURRENT (nA) 50 6 Input overdrive : 100mV 5 4 5mV 3 2 20mV 1 0 100 Tamb = +25°C 50 0 0 0.5 1 1.5 TIME (m s) 5V 5.1kW eI eo 2 LM2903H PACKAGE MECHANICAL DATA SO-8 MECHANICAL DATA DIM. mm.
