OPA1013

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.

APPLICATIONS

● PRECISION INSTRUMENTATION

● BATTERY-POWERED EQUIPMENT

● BRIDGE AMPLIFIERS

● 4-20mA CURRENT TRANSMITTERS

● VOLTAGE COMPARATOR

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.
