AD7606BSTZ-RL - 16-Bit 8-Ch Simultaneous ADC | Analog Devices
MPN: AD7606BSTZ-RL ✓ Hoạt độngAD7606BSTZ-RL Tóm tắt
A data acquisition system (DAS) is a complete signal chain that conditions, samples, and converts analog signals into digital data for processing. The AD7606 integrates the entire front-end, eliminating the need for external op-amps, references, and antialiasing filters, thereby reducing board space and design complexity. As a simultaneous sampling ADC, it captures all channels at the same instant, which is critical for applications requiring phase-accurate measurements across multiple inputs.
Key features include a 200 kSPS throughput rate per channel, 16-bit resolution with no missing codes, and a 2.5 V internal reference with ±1% accuracy. The device offers both serial (SPI/QSPI/MICROWIRE) and parallel interfaces, and supports daisy-chaining for multiple devices. The flexible digital filter can be configured to improve noise performance, and the analog input clamp protects against overvoltage conditions up to ±16.5 V.
The AD7606 uses a charge redistribution SAR architecture, which provides excellent linearity and low power consumption. The integrated antialiasing filter simplifies external filtering requirements, and the track-and-hold amplifier ensures accurate sampling of fast-changing signals. The device operates over the industrial temperature range of -40°C to +85°C and is available in a 64-lead LQFP package.
Typical applications include power line monitoring, protective relays, motor control, and multi-phase energy measurement. The simultaneous sampling capability ensures accurate phase relationships between channels, which is essential for power quality analysis. The device is also suitable for vibration analysis and other multi-channel data acquisition systems.
When designing with the AD7606, ensure that the analog input range is properly configured via the RANGE pin, and that the reference decoupling capacitor is placed close to the REFIN/REFOUT pin. The digital interface should be matched to the host processor's voltage level, and the AVCC and DVCC supplies should be decoupled with 0.1 µF and 10 µF capacitors.

Ghi chú thiết kế
The AD7606BSTZ-RL requires a clean 5 V analog supply (AVCC) and a separate digital supply (VDRIVE) from 2.3 V to 5 V. Decouple AVCC and DVCC with 0.1 µF and 10 µF capacitors placed close to the pins. The internal reference (REFOUT/REFIN) should be decoupled with a 1 µF capacitor to ground to ensure stability and low noise.
Place the AD7606BSTZ-RL on a PCB with a solid ground plane. The exposed pad (EP) must be soldered to the ground plane for proper thermal and electrical performance. Keep analog and digital grounds separate and connect them at a single point. Route analog inputs away from digital traces to minimize noise coupling.
Ensure the RANGE pin is set correctly for the desired input voltage range (±5 V or ±10 V). Incorrect setting can lead to clipping or damage. Also, the CONVST A and CONVST B pins must be triggered simultaneously for true simultaneous sampling. Avoid floating unused digital inputs; tie them to appropriate logic levels.
