AD73360LARZ-REEL

Overview

The AD73360LARZ-REEL is a six-channel analog front-end processor featuring six independent 16-bit sigma-delta ADCs. It provides simultaneous sampling with a maximum sample rate of 64 kS/s and a typical signal-to-noise ratio of 77 dB over a DC to 4 kHz bandwidth. Each channel includes a programmable gain amplifier (PGA) with eight gain stages from 0 dB to 38 dB. The device 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. It incorporates an on-chip reference voltage and utilizes a flexible serial port for cascading multiple devices.

Feature Summary

• Six 16-bit A/D converters with simultaneous sampling capability
• Programmable input gain amplifier (PGA) with settings from 0 dB to 38 dB
• On-chip reference voltage with selectable 1.25 V or 2.5 V output
• Flexible serial port supporting cascade connections up to eight devices

Applications

• Industrial power metering
• General purpose analog input systems
• Motor control applications
• Simultaneous sampling data acquisition

Procurement Notes

Verify the 'L' suffix in the part number against official Analog Devices documentation, as standard listings typically use 'ARZ'. Confirm current availability status, as the AD73360 family may have discontinuation notices. Ensure the REEL packaging matches production line requirements. Cross-reference the specific revision level required for the design.

Selection Notes

Select this component when multi-channel synchronous sampling is required with integrated signal conditioning. The internal PGA reduces the need for external amplifiers. Ensure the master clock frequency supports the desired sample rates (8 kHz, 16 kHz, 32 kHz, or 64 kHz). Verify that the digital interface timing aligns with the host DSP or microcontroller capabilities.

Part Context

The AD73360 belongs to the Analog Devices family of high-performance analog front ends designed for industrial applications. It integrates signal conditioning, programmable gain, and sigma-delta conversion into a single package. The device simplifies system design by combining multiple functions typically found in discrete solutions, offering low group delay and high crosstalk rejection.

Replacement Considerations

Check for direct pin-compatible alternatives within the AD73360 series, such as AD73360ARZ or AD73360AR. Evaluate if newer generations from Analog Devices offer improved specifications or extended availability. Ensure any substitute maintains the six-channel architecture and 16-bit resolution requirements.
