AD7606BSTZ-4

ADCs/DACs - Special Purpose Overview

The AD7606BSTZ-4 is a 16-bit, four-channel simultaneous sampling analog-to-digital data acquisition system (DAS) from Analog Devices. It integrates an ADC core, track-and-hold amplifier, second-order antialiasing filter, and a 2.5 V reference buffer. Operating on a single 5 V supply, it supports ±10 V and ±5 V bipolar input ranges with up to 200 kSPS throughput per channel. Key electrical parameters include a typical SNR of 95.5 dB, ±0.5 LSB INL/DNL, and 1 MΩ input impedance. The device features clamp protection for inputs up to ±16.5 V and operates within a temperature range of −40°C to +85°C.

ADCs/DACs - Special Purpose Feature Summary

• Four-channel simultaneous sampling at 200 kSPS with true bipolar input ranges of ±10 V or ±5 V.
• Integrated second-order antialiasing filter with 22 kHz cutoff and flexible digital oversampling filter.
• Supports parallel, serial, and byte-mode interfaces compatible with SPI/QSPI/MICROWIRE/DSP standards.
• Includes internal 2.5 V reference, 1 MΩ input impedance, and ±16.5 V analog input clamp protection.

ADCs/DACs - Special Purpose Applications

• Power-line monitoring and protection systems
• Multiphase motor control
• Instrumentation and control systems
• Multiaxis positioning systems
• Data acquisition systems (DAS)

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'BSTZ-4' against the manufacturer's current ordering guide to confirm package type and tape/reel specifications. Ensure compatibility with the host logic voltage levels, as the VDRIVE supply must be between 2.3 V and 5.25 V. Confirm that the design accounts for the 64-lead LQFP thermal requirements and ESD sensitivity during handling.

ADCs/DACs - Special Purpose Selection Notes

Select this component when four synchronized channels are required for high-precision acquisition. The AD7606-4 variant reduces pin count compared to the 8-channel AD7606 while maintaining identical performance metrics. Consider the integrated antialiasing filter if external filtering components are to be minimized. Verify that the system power budget accommodates approximately 111 mW operational dissipation.

ADCs/DACs - Special Purpose Part Context

This part belongs to the AD7606 family, which also includes the 8-channel AD7606 and 6-channel AD7606-6. All variants share the same architecture, pinout structure, and electrical characteristics, differing only in the number of analog input channels. This allows for design scalability across different channel count requirements without changing the core ADC solution.

ADCs/DACs - Special Purpose Replacement Considerations

The datasheet identifies the AD7606B as a state-of-the-art alternative recommended for new designs. While pin-compatible, verify specific parameter updates and availability before substitution. No other direct cross-model replacements are explicitly listed in the provided documentation.
