The OPA1013 dual operaTIonal amplifier providesprecision performance in single power supply and lowpower applicaTIons. It is laser trimmed for low offsetvoltage and drift, greatly reducing the large errorscommon with LM324-type op amps. Input offsetcurrent is also trimmed to reduce errors in high impedanceapplicaTIons. The OPA1013 is characterized for operaTIon at both+5V (single supply) and ±15V power supplies. Whenoperated from a single supply, the input common-moderange includes ground and the output can swing towithin 15mV of ground. Completely independent biasingnetworks eliminate interaction between the twoamplifiers—even when one is used as a comparator.The OPA1013 is available in an 8-pin plastic DIPspecified for the 0°C to +70°C temperature range.
