AD73460BB-80

Overview

The AD73460BB-80 is a six-input channel analog front-end processor integrating an ADSP-2100 base architecture DSP. It features six simultaneous sampling 16-bit A/D converters with 72 dB SNR and programmable gain amplifiers (0 to 38 dB). The device operates on a single supply, supports sample rates up to 64 kS/s, and includes 80 K bytes of on-chip memory (16K words program RAM, 16K words data RAM). Designed for industrial power metering, it ensures synchronous sampling with low group delay.

Feature Summary

• Six 16-bit A/D converters with simultaneous sampling capability
• Integrated ADSP-2100 DSP engine with 52 MIPS sustained performance
• 80 K bytes on-chip memory (16K PM/16K DM)
• Programmable input gain amplifier (PGA) with eight stages from 0 dB to 38 dB

Applications

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

Procurement Notes

Verify the specific suffix BB-80 against the manufacturer's ordering guide to confirm the 119-ball PBGA package and 80 K byte memory configuration. Ensure compatibility with the -40°C to +85°C industrial temperature range specifications during procurement planning.

Selection Notes

Select this component when simultaneous multi-channel acquisition is required without phase delay between channels. The integrated DSP allows for local signal processing, reducing external controller load. Verify that the 80 K byte internal memory suffices for the application's algorithm requirements before choosing over the 40 K variant.

Part Context

This part belongs to the Analog Devices AD73460 family of analog front-end processors. It combines high-performance sigma-delta ADCs with a dedicated digital signal processor in a single package, simplifying system design for precision measurement applications compared to discrete solutions.

Replacement Considerations

The AD73460BB-40 offers identical functionality but with reduced on-chip memory (40 K bytes total). External cascading with AD73360 devices can expand channel count if more than six inputs are needed.
