AD7606BSTZ-6

ADCs/DACs - Special Purpose Overview

The AD7606BSTZ-6 is a 16-bit, six-channel simultaneous sampling analog-to-digital data acquisition system (DAS) manufactured by Analog Devices Inc. Operating from a single 5 V supply, it supports true bipolar input ranges of ±10 V and ±5 V with a maximum throughput rate of 200 kSPS per channel. The device integrates an analog input clamp protection circuit capable of tolerating up to ±16.5 V, a second-order antialiasing filter with a 22 kHz cutoff frequency, and a 2.5 V internal reference. It features a 1 MΩ analog input impedance, eliminating the need for external driver amplifiers. The ADC utilizes a charge redistribution successive approximation architecture, providing 95.5 dB SNR and −107 dB THD.

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 ordering suffix to confirm package type and reel quantity. The standard BSTZ designation indicates a 64-lead LQFP package. Confirm that the required logic voltage levels align with the VDRIVE range of 2.3 V to 5.25 V for your host interface. Ensure proper decoupling capacitors are placed near AVCC and VDRIVE pins during PCB layout to maintain signal integrity.

ADCs/DACs - Special Purpose Selection Notes

Select the AD7606BSTZ-6 when six synchronized channels are required within a 16-bit resolution constraint. Compare against the AD7606 (8-channel) or AD7606-4 (4-channel) if channel count requirements differ. Consider the AD7606B series for newer designs requiring pin-compatible upgrades. Evaluate power consumption needs, as operational power reaches 126 mW at full speed, while standby mode reduces this to 42 mW.

ADCs/DACs - Special Purpose Part Context

The AD7606BSTZ-6 belongs to the AD7606 family of high-resolution, simultaneous sampling DAS devices. This family includes the 8-channel AD7606 and the 4-channel AD7606-4, all sharing identical core architectures and peripheral integration. The 'B' suffix denotes a version compatible with the state-of-the-art AD7606B, offering enhanced performance metrics while maintaining pin compatibility across the series.

ADCs/DACs - Special Purpose Replacement Considerations

The AD7606B is recommended as a direct pin-compatible alternative for new designs. For applications requiring eight channels, the AD7606BSTZ serves as the expanded counterpart. If four channels suffice, the AD7606BSTZ-4 provides a smaller footprint option with identical electrical characteristics.
