AD7606BSTZ 概要
A data acquisition system (DAS) is a complete signal chain that conditions, samples, and digitizes analog signals. The AD7606BSTZ belongs to the family of simultaneous sampling ADCs, which capture multiple channels at the same instant, preserving phase relationships critical for power metering and vibration analysis. It sits between analog sensors and a digital host processor, converting real-world signals into digital words for processing.
Key features include 16-bit resolution, 200 kSPS throughput per channel, 8 simultaneous sampling channels, and a 64-lead LQFP package. The device offers a parallel, serial, SPI, QSPI, and MICROWIRE interface, providing flexibility for various host controllers. The integrated 2.5V reference and buffer eliminate the need for external reference components, simplifying design and reducing BOM cost.
Technically, the AD7606BSTZ uses a successive approximation register (SAR) architecture with a charge redistribution DAC. The analog front end includes a second-order antialiasing filter with a cutoff frequency of 22 kHz, which attenuates out-of-band noise. The digital filter provides programmable oversampling ratios to further reduce noise. The device operates over the industrial temperature range of -40°C to +85°C and is available in a 10x10 mm LQFP package.
Typical applications include power-line monitoring, protective relays, motor control, and multi-axis vibration analysis. The simultaneous sampling capability ensures accurate phase measurement between voltage and current channels, which is essential for power quality analysis. The high input impedance and integrated protection make it robust for harsh industrial environments.
When designing with the AD7606BSTZ, ensure proper decoupling of the AVCC and DVCC supplies with 10 µF and 0.1 µF capacitors placed close to the pins. The REFIN/REFOUT pin can be driven by an external reference if higher accuracy is required, but the internal 2.5V reference is sufficient for most applications. The CONVST pins should be driven simultaneously to achieve true simultaneous sampling.

設計ノート
Decouple the AVCC and DVCC supplies with 10 µF and 0.1 µF capacitors placed as close to the pins as possible. The AVCC supply should be clean and stable, as noise on the analog supply directly affects conversion accuracy. Use a low-noise LDO regulator to power AVCC if the system has switching regulators. The VDRIVE pin should be connected to the same supply as the host interface logic to ensure proper voltage levels.
Place the AD7606BSTZ on a PCB with a solid ground plane. Separate analog and digital ground planes and connect them at a single point near the ADC. Keep analog input traces short and shielded to minimize noise pickup. Use a ground plane under the analog input section to reduce parasitic capacitance. The REFIN/REFOUT pin should have a 10 µF capacitor to ground for stability.
Ensure the CONVST A and CONVST B pins are driven simultaneously to achieve true simultaneous sampling. If they are driven separately, the samples will not be aligned in time, which can cause phase errors in multi-channel measurements. Also, avoid exceeding the absolute maximum ratings on the analog inputs, as the internal clamp protection has limits. Use series resistors to limit current if overvoltage is expected.
