OP727AR

Instrumentation, Op Amps, Buffer Amps Overview

The OP727AR is a dual precision operational amplifier from Analog Devices, featuring micropower operation and rail-to-rail output ranges. It provides improved performance over the industry-standard OP07 with ±15 V supplies and offers true single-supply operation down to 3 V. The device includes built-in 500 Ω internal current limiting resistors for input protection. Key electrical specifications include a maximum offset voltage of 160 μV at +25°C and 300 μV across the industrial temperature range (-40°C to +85°C). Input bias current is limited to 10 nA maximum. Supply current per amplifier is typically 320 μA at 5 V. The gain bandwidth product is 0.7 MHz, and the slew rate is 0.2 V/μs.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Features rail-to-rail output capability allowing signals to swing within 1 mV of both supply rails.
• Includes built-in 500 Ω series input resistors to protect against damage from overvoltage conditions.
• Operates stably with capacitive loads exceeding 500 pF without phase reversal issues.
• Utilizes a precision Bipolar PNP input stage coupled with a high-voltage CMOS output stage.

Instrumentation, Op Amps, Buffer Amps Applications

• Current sensing using shunt resistors
• Line or battery-powered instrumentation
• Remote sensor signal conditioning
• Precision filters

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific package option, as the OP727 family includes SOIC and TSSOP variants with distinct pinouts. Confirm RoHS compliance status if required by the design specification. Ensure the selected part number matches the desired tape and reel or tube packaging format. Cross-reference the ordering guide to confirm the suffix indicates the correct physical package dimensions and lead finish.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when single-supply operation is required alongside precision requirements. The OP727AR serves as a pin-compatible replacement for the LT1013 in 8-lead SOIC configurations. Consider the unique pinout of the 8-lead SOIC variant compared to standard op-amp layouts. Evaluate the low supply current consumption for battery-operated applications requiring extended runtime.

Instrumentation, Op Amps, Buffer Amps Part Context

The OP727AR belongs to the OP777/OP727/OP747 series of precision micropower single-supply operational amplifiers manufactured by Analog Devices. This series is designed to replace older bipolar amplifiers like the OP07 while offering superior input and output voltage ranges. The dual configuration (OP727) is available in 8-lead TSSOP and 8-lead SOIC packages, catering to surface-mount assembly needs.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The OP727AR in 8-lead SOIC is pin-compatible with the LT1013. Designers should verify that the target application can accommodate the non-standard pinout of the 8-lead SOIC package compared to conventional dual op-amps.
