DESCRIPTION
The OPA1013 dual operational amplifier provides
precision performance in single power supply and low
power applications. It is laser trimmed for low offset
voltage and drift, greatly reducing the large errors
common with LM324-type op amps. Input offset
current is also trimmed to reduce errors in high im-
pedance applications.
The OPA1013 is characterized for operation at both
+5V (single supply) and ±15V power supplies. When
operated from a single supply, the input common-mode
range includes ground and the output can swing to
within 15mV of ground. Completely independent bias-
ing networks eliminate interaction between the two
amplifiers—even when one is used as a comparator.
The OPA1013 is available in an 8-pin plastic DIP
specified for the 0°C to +70°C temperature range.

INPUT PROTECTION
APPLICATIONS INFORMATION
The circuitry of the OPA1013 is protected against overload
for input voltages ranging from the positive supply voltage
to 5V below the negative supply voltage (below ground in
single supply operation). No external protection circuitry is
required, as it is with other common single-supply op amps.
The OPA1013 is unity-gain stable, making it easy to use and
free from oscillations in the widest range of circuitry. Follow
good design practice by bypassing the power supplies close
to the op amp pins. In most cases 0.1µF ceramic capacitors
are adequate.
Furthermore, the OPA1013 is free from phase-reversal prob-
lems common with other single-supply op amps. When the
inputs are driven below ground (or below the negative
power supply), the output polarity remains correct.
SINGLE POWER SUPPLY OPERATION
The OPA1013 is specified for operation from a single power
supply. This means that linear operation continues with the
input terminals at (or even somewhat below) ground poten-
tial. When used in a non-inverting amplifier, 0V input must
produce 0V output. In practice, the output swing is limited
to approximately 15mV above ground with no load. Output
swing near ground can be optimized when the output load is
connected to ground. If the output must sink current, the
ability to swing near ground will be diminished. The output
swings to within approximately 200mV of ground when
sinking 1mA.
COMPARATOR OPERATION
The OPA1013 functions well as a comparator, where high
speed is not required. Sometimes, in fact, the low offset and
docile characteristics of the OPA1013 may simplify the
design of comparator circuitry. The two op amps in the
OPA1013 use completely independent bias circuitry to avoid
interaction when the inputs are over-driven. Driving one op
amp into saturation will not affect the characteristics of the
other amplifier. The outputs of the OPA1013 can drive one
TTL load. Quiescent current remains stable when the inputs
are overdriven.
