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.
