AD73360ARZ

Overview

The AD73360ARZ is a six-channel analog front-end processor featuring 16-bit sigma-delta ADCs. It provides simultaneous sampling with a maximum rate of 64 kS/s and 77 dB SNR. Each channel includes a programmable gain amplifier (PGA) with settings from 0 dB to 38 dB. The device operates on a single supply voltage ranging from +2.7 V to +5.5 V, consuming a maximum of 80 mW at 2.7 V. It integrates an on-chip reference and utilizes a flexible serial port for cascading multiple units.

Feature Summary

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

Applications

• Industrial power metering systems requiring synchronous multi-channel acquisition
• General-purpose analog input modules for data acquisition
• Motor control applications needing precise current/voltage sensing
• Simultaneous sampling environments where phase alignment between channels is critical

Procurement Notes

Verify the specific suffix ARZ indicates the RoHS-compliant version in the 28-lead SOIC package. Confirm the operating temperature range matches the industrial specification (-40°C to +85°C). Check for any discontinuation notices or end-of-life status as availability may be limited. Ensure the host system supports the required serial clock and master clock frequencies for the desired sample rate.

Selection Notes

Select this component when six synchronized 16-bit channels are required within a single IC. The internal PGA reduces the need for external amplifiers, simplifying board design. Consider the 28-lead SOIC package constraints for PCB layout. Verify that the host DSP or microcontroller can handle the SPORT interface timing requirements, including the SCLK and MCLK relationships defined in the datasheet.

Part Context

The AD73360 belongs to Analog Devices' family of high-performance analog front-end processors designed for multichannel applications. The ARZ suffix denotes the lead-free, RoHS-compliant variant packaged in a 28-lead Small Outline Integrated Circuit (SOIC). This part is distinct from other ADCs by integrating signal conditioning, PGA, and digital filtering on a single chip.

Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation. Designers should evaluate other Analog Devices AFEs or multi-channel ADCs if the AD73360 is unavailable, ensuring compatibility with the existing serial interface and pinout requirements.
