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.
