LOW POWER DUAL OP-AMP
INTERNALLY FREQUENCY COMPENSATED LARGE DC VOLTAGE GAIN : 100dB WIDE BANDWIDTH (unity gain): 1.1MHz(temperature compensated) VERY LOW SUPPLY CURRENT/OP (500μA)
ESSENTIALLY INDEPENDENT OF SUPPLY
VOLTAGE LOW INPUT BIAS CURRENT: 20nA
(temperature compensated) LOW INPUT OFFSET CURRENT: 2nA INPUT COMMON-MODE VOLTAGE RANGE
INCLUDES GROUND DIFFERENTIAL INPUT VOLTAGE RANGE
EQUAL TO THE POWER SUPPLY VOLTAGE LARGE OUTPUT VOLTAGE SWING 0V TO
(VCC - 1.5V)
DESCRIPTION This circuit consists of two independent, high gain,
internally frequency compensated which were de-
signed specifically for automotive and industrial
control system. It operates from a single power
supply over a wide range of voltages. The low
power supply drain is independent of the magni-
tude of the power supply voltage.
Application areas include transducer amplifiers,
dc gain blocks and all the conventional op-amp
circuits which now can be more easily implement-
ed in single power supply ssystems. For example,
these circuits can be directly supplied with off the
standard +5V which is used in logic systems and
will easily provide the required interface electron-
ics without requiring any additional power supply.
In the linear mode the input common-mode volt-
age range includes ground and the output voltage
can also swing to groung, even though operated
from only a single power supply voltage.

SCHEMATIC DIAGRAM (1/2 LM2904)
ABSOLUTE MAXIMUM RATINGS Short-circuits from the output to Vcc can cause excessive heating if Vcc+ > 15V. The maximum output current is approximately 40mA,
independent of the magnitude of Vcc. Destructive dissipation can result from simultaneous short-circuits on all amplifiers. Power dissipation must be considered to ensure maximum junction temperature (Tj) is not exceeded. This input current only exists when the voltage at any of the input leads is driven negative. It is due to the collector-base junction of the input PNP
transistor becoming forward biased and thereby acting as input diodes clamps. In addition to this diode action, there is also NPN parasitic action on
the IC chip. This transistor action can cause the output voltages of the Op-Amps to go to the VCC voltage level (or to ground for a large overdrive)
for the time duration than an input is driven negative. This is not destructive and normal output will set up again for input voltage higher than -0.3V.

ELECTRICAL CHARACTERISTICSVCC+ = 5V, Vcc- = Ground, VO = 1.4V, Tamb = 25°C (unless otherwise specified)
LM2904
VO = 1.4V, RS = 0Ω, 5V < VCC+ < 30V, 0V < Vic < VCC+ - 1.5V The direction of the input current is out of the IC. This current is essentially constant, independent of the state of the output, so no loading chargechange exists on the input lines 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 thecommon-mode voltage range is VCC + –1.5V, but either or both inputs can go to +32V without damage. Due to the proximity of external components insure that coupling is not originating via stray capacitance between these external parts. This typicallycan be detected as this type of capacitance increases at higher frequences.
