AD73360ASUZ

Overview

The AD73360ASUZ is a six-channel analog front-end processor in a 44-lead TQFP package. It integrates six 16-bit sigma-delta ADCs with programmable gain amplifiers (PGA) offering gains from 0 dB to 38 dB. The device supports simultaneous sampling across all channels, ensuring zero phase delay between conversions. It operates on a single supply voltage ranging from +2.7 V to +5.5 V, with maximum power consumption of 80 mW at 2.7 V. Key electrical specifications include a signal-to-noise ratio of 77 dB and a maximum sample rate of 64 kS/s.

Feature Summary

• Six independent 16-bit A/D conversion channels with simultaneous sampling capability
• Integrated programmable input gain amplifier (PGA) with eight gain stages (0 dB to 38 dB)
• On-chip bandgap voltage reference with selectable output levels of 1.25 V or 2.5 V
• Flexible serial port supporting cascade connections of up to eight devices

Applications

• Industrial power metering
• General purpose analog input systems
• Motor control applications
• Multichannel simultaneous sampling systems

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm the specific suffix ASUZ corresponds to the 44-lead TQFP package variant. Check for moisture sensitivity handling requirements during storage and assembly. Ensure compatibility with the intended operating temperature range of -40°C to +85°C.

Selection Notes

Select this component when multi-channel synchronous acquisition is required. Verify that the input signal range fits within the PGA-adjusted limits for the chosen gain setting. Ensure the host processor interface supports the required serial clock rates and frame synchronization protocols. Consider the thermal impedance of the TQFP package for heat dissipation in enclosed environments.

Part Context

The AD73360 series includes variants such as the AD73360ARZ in a 28-lead SOIC package. The ASUZ suffix specifically denotes the 44-lead Thin Quad Flat Package (TQFP). All variants share identical internal architecture and functional specifications, differing only in physical footprint and pin count.

Replacement Considerations

The AD73360ARZ serves as a direct pin-compatible alternative if the 28-lead SOIC package is preferred, though it requires board layout changes due to different pin counts. No other direct substitutes are documented in the provided source material.
