AD734ANZ

Overview

The AD734ANZ is a high-speed, four-quadrant analog multiplier and divider manufactured by Analog Devices Inc. It operates within a supply voltage range of 8 V to 16.5 V and functions across an extended temperature range from -55 °C to +125 °C. The device features a full power bandwidth of 10 MHz with a slew rate of 450 V/μs. Total static error is typically 0.1% of full scale, and distortion is guaranteed at less than -80 dBc. It utilizes a 14-pin PDIP package and draws 9 mA of operating current.

Feature Summary

• Supports direct division mode allowing external control of the denominator voltage for flexible system design
• Features advanced output amplifier design providing significantly higher slew rate compared to legacy counterparts
• Utilizes fully differential low capacitance inputs to minimize external component requirements
• Employs novel laser trimming techniques based on AC signals to ensure high precision

Applications

• Gamma camera position circuitry for medical imaging diagnostics
• High-frequency demodulation with input frequencies up to 40 MHz
• Precision amplitude modulation and signal processing systems
• Broadband gain control and automatic gain control loops

Procurement Notes

Verify specific ordering suffixes against official Analog Devices documentation to confirm exact temperature grades and packaging types. Confirm availability status directly with authorized distributors as stock levels fluctuate. Ensure the selected variant matches the required industrial or military temperature specifications for your application environment before finalizing procurement orders.

Selection Notes

Select the AD734ANZ when high-speed operation and low distortion are critical requirements. This component serves as a pin-compatible upgrade to older industry-standard multipliers, offering superior bandwidth and transient response. Evaluate the need for direct denominator control if variable gain or division ratios are required in the signal chain architecture.

Part Context

The AD734 series represents a class of precision analog computation devices designed for demanding signal processing tasks. It maintains compatibility with previous generations while introducing significant performance improvements through complementary bipolar processes. The device family includes variants specified for different temperature ranges and packaging styles to suit diverse industrial and commercial deployment scenarios.

Replacement Considerations

The AD734 is pin-compatible with the AD534. Designers upgrading from AD534 should verify that the increased slew rate and bandwidth do not require adjustments to existing compensation networks or layout constraints.
