AD734AN

Overview

The AD734AN is a high-speed, four-quadrant analog multiplier and divider manufactured by Analog Devices. It provides the transfer function W = XY/U with a low-impedance voltage output. The device features a full-power bandwidth of 10 MHz for a 20 V p-p signal and a typical total static error of 0.1%. It includes a new direct division mode allowing external denominator control, maintaining signal bandwidth up to 10 MHz at lower gains. Key electrical specifications include a 450 V/μs slew rate, settling time of 200 ns to 0.1%, and distortion typically less than -80 dBc. Supply voltage ranges from 8 V to 16.5 V.

Feature Summary

• High accuracy with 0.1% typical total static error
• Direct division mode enabling external denominator voltage control
• Low distortion performance typically below -80 dBc
• High slew rate of 450 V/μs for fast transient response

Applications

• Modulators and demodulators
• Broadband gain controllers
• DC RMS-to-DC converters
• Voltage-controlled amplifiers
• Oscillators and filters

Procurement Notes

Verify the specific suffix 'AN' indicates the standard plastic DIP-14 package variant when ordering. Confirm supply availability as distribution status may vary. Ensure design compatibility with the required operating temperature range and power supply voltages specified in the official datasheet before finalizing procurement decisions.

Selection Notes

Select the AD734AN when pin-compatible replacement for the industry-standard AD534 is required but higher speed and lower distortion are needed. Choose this component for applications demanding direct external control of the denominator voltage in division modes. Consider the 10 MHz full-power bandwidth and low noise characteristics for precision signal processing tasks requiring high dynamic range.

Part Context

The AD734 series represents an evolution in analog multiplier technology, offering significant improvements over previous generations like the AD534. It integrates a buried-Zener voltage reference for internal scaling while providing flexibility through external denominator inputs. The device is designed for precision instrumentation and communication systems where linearity and speed are critical performance factors.

Replacement Considerations

The AD734AN is pin-compatible with the AD534. When substituting, verify that the application benefits from the improved 450 V/μs slew rate and lower distortion characteristics compared to the legacy device.
