AD73360ASUZ-REEL

Overview

The AD73360ASUZ-REEL 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. Key electrical parameters include a maximum sample rate of 64 kS/s, a signal-to-noise ratio of 77 dB, and crosstalk below -83 dB. It operates on a single supply voltage ranging from +2.7 V to +5.5 V, with a maximum power consumption of 80 mW at 2.7 V.

Feature Summary

• Six independent 16-bit A/D conversion channels with simultaneous sampling capability
• Programmable input gain amplifier (PGA) with eight stages from 0 dB to 38 dB
• On-chip bandgap voltage reference with selectable 1.25 V or 2.5 V output
• 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 the REEL suffix indicates tape-and-reel packaging for automated assembly. Confirm the 'A' grade designation ensures operation within the specified industrial temperature range of -40°C to +85°C. Check current availability status as discontinuation notices may affect long-term sourcing.

Selection Notes

Select this component when multi-channel synchronous acquisition is required without external timing synchronization circuits. Ensure the master clock frequency matches the required sample rate settings of 8 kHz, 16 kHz, 32 kHz, or 64 kHz. Verify that the input signal range fits within the PGA-adjusted limits for the chosen supply voltage configuration.

Part Context

The AD73360ASUZ-REEL belongs to the Analog Devices AD73360 family of analog front ends. It shares core functionality with the AD73360ARZ but differs in package type (TQFP vs. SOIC) and reel packaging format. This specific part number represents the industrial grade variant optimized for high-density PCB layouts requiring surface mount technology.

Replacement Considerations

Direct pin-compatible replacements are limited due to the specific combination of six-channel architecture and TQFP-44 packaging. Evaluate the AD73360ARZ only if redesigning for a 28-lead SOIC footprint is acceptable. No other Analog Devices parts offer identical six-channel simultaneous sampling in this package.
