AD73460BB-40

Overview

The AD73460BB-40 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 a maximum sample rate of 64 kS/s and 72 dB SNR. Each channel includes a programmable gain amplifier (PGA) with eight stages from 0 dB to 38 dB. The device contains 40 KB of on-chip memory, configured as 8K words of program RAM and 8K words of data RAM. It operates on a single supply voltage between +2.7 V and +5.5 V.

Feature Summary

• Six-channel simultaneous sampling with 16-bit resolution and 72 dB SNR
• Integrated ADSP-2100 DSP engine with 52 MIPS sustained performance
• 40 KB on-chip memory (8K PM / 8K DM)
• Programmable input gain amplifiers (0 dB to 38 dB)

Applications

• Industrial power metering
• Multichannel analog input systems

Procurement Notes

Verify the specific suffix BB-40 against official Analog Devices documentation to confirm the 40 KB memory configuration and industrial temperature range (-40°C to +85°C). Ensure compatibility with the 119-ball PBGA package requirements for your design.

Selection Notes

Select this component when simultaneous multi-channel acquisition is required without phase delay. The integrated DSP allows for local signal processing, reducing external controller load. Verify that the 40 KB internal memory suffices for your application's code and data storage needs before choosing over the 80 KB variant.

Part Context

This part belongs to the AD73460 family of analog front-end processors. It shares the same core AFE and DSP architecture as the AD73460BB-80 but differs in the amount of onboard program and data RAM. It is designed for applications requiring high-speed, synchronized data acquisition with embedded processing capabilities.

Replacement Considerations

The AD73460BB-80 is a direct pin-compatible alternative offering increased memory (80 KB total). No other public substitutes are confirmed in the provided documentation.
