OP213FPZ

Instrumentation, Op Amps, Buffer Amps Overview

The OP213FPZ is a dual-channel, low-noise, low-drift operational amplifier from Analog Devices Inc., designed for single-supply operation. It features a gain bandwidth product of 3.4 MHz and a slew rate of 1.2 V/µs. The device exhibits a maximum input offset voltage of 100 µV and a drift coefficient of 0.8 µV/°C. Input voltage noise density is 4.7 nV/√Hz at 1 kHz. It operates on a single supply of 4 V to 36 V or dual supplies of ±2 V to ±18 V. The unit draws approximately 3.8 mA per amplifier at ±15 V. Common mode rejection ratio ranges from 100 dB to 116 dB, while power supply rejection ratio is between 97 dB and 103 dB.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'FPZ' indicates an 8-pin PDIP package when ordering. Confirm RoHS compliance status through official manufacturer documentation. Ensure the operating temperature range meets system requirements, typically -40°C to +85°C. Cross-reference pinouts if replacing legacy components. Validate datasheet revisions for any parameter updates before final design integration.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when low noise and low drift are critical in single-supply environments. It is suitable for applications requiring high DC accuracy where processor-based calibration handles offset but not thermal drift. Consider the 3.4 MHz bandwidth for moderate speed requirements. Evaluate power consumption against battery life constraints in portable devices.

Instrumentation, Op Amps, Buffer Amps Part Context

The OP213FPZ belongs to the OPx13 family of single-supply operational amplifiers manufactured by Analog Devices Inc. This series is optimized for precision applications requiring stability over temperature variations. The FPZ designation specifically denotes the plastic dual in-line package variant within the broader OP213 product line.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

OP213FSZ serves as a direct functional substitute with identical electrical characteristics but utilizes an SOIC-8 surface-mount package instead of the PDIP form factor.
