AD7608BSTZ-RL

ADCs/DACs - Special Purpose Overview

The AD7608BSTZ-RL is an 18-bit, 8-channel simultaneous sampling analog-to-digital data acquisition system (DAS) manufactured by Analog Devices Inc. It integrates analog input clamp protection, a second-order antialiasing filter, track-and-hold amplifiers, and a charge redistribution SAR ADC. The device operates from a single 5 V analog supply and accepts true bipolar input ranges of ±10 V or ±5 V with a 1 MΩ input impedance. It supports throughput rates up to 200 kSPS across all channels and features flexible parallel or serial digital interfaces.

ADCs/DACs - Special Purpose Feature Summary

• 18-bit resolution with 200 kSPS throughput on all eight channels
• Integrated second-order antialiasing filter with 22 kHz cutoff frequency
• True bipolar input ranges: ±10 V or ±5 V selectable via RANGE pin
• Input clamp protection tolerating voltages up to ±16.5 V

ADCs/DACs - Special Purpose Applications

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

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'BSTZ-RL' against the manufacturer's current ordering guide to confirm package type, temperature range, and reel packaging specifications. Ensure compatibility with host interface voltage levels (VDRIVE) ranging from 2.3 V to 5.25 V during integration.

ADCs/DACs - Special Purpose Selection Notes

Select this component for applications requiring high channel count and simultaneous sampling without external multiplexers. The integrated 2.5 V reference and buffer simplify design compared to discrete solutions. Consider the 100 mW power dissipation in thermal management calculations for dense PCB layouts.

ADCs/DACs - Special Purpose Part Context

This part belongs to the AD7608 family of high-resolution DAS devices. It offers pin-compatible alternatives within the AD7606 and AD7609 series for designs requiring different resolutions (16-bit or 14-bit) or channel counts. The BSTZ-RL designation indicates a specific surface-mount package variant intended for automated assembly.

ADCs/DACs - Special Purpose Replacement Considerations

Pin-compatible substitutes include the AD7606 (16-bit) and AD7609 (18-bit). Verify that the replacement device meets the required 200 kSPS simultaneous sampling rate and input voltage tolerance specifications.
