Typical Applications
AD7606BSTZ is suitable for 6 applications: Power Line Monitoring, Protective Relays, Motor Control, Multi-Axis Vibration Analysis, Data Acquisition Systems, Medical Monitoring.
Power Line Monitoring
The AD7606BSTZ is ideal for power line monitoring systems that require simultaneous sampling of multiple voltage and current channels. Its 16-bit resolution and 200 kSPS sampling rate capture harmonic content accurately, while the integrated antialiasing filter and 2.5V reference simplify the signal chain. The device's bipolar input range of Β±10V directly interfaces with voltage transformers and current transformers, reducing external conditioning circuitry. The simultaneous sampling ensures precise phase measurement between channels, which is critical for power quality analysis and revenue metering. The industrial temperature range and robust input protection make it suitable for outdoor substation environments.
Recommended
Protective Relays
In protective relays, the AD7606BSTZ provides fast and accurate simultaneous sampling of voltage and current waveforms to detect faults. The 200 kSPS sampling rate and 16-bit resolution enable precise measurement of transient events, while the integrated antialiasing filter prevents aliasing of high-frequency noise. The device's parallel interface allows high-speed data transfer to the relay's DSP or microcontroller, ensuring timely trip decisions. The wide input range and clamp protection handle overvoltage conditions without external protection components. The industrial temperature range and high reliability make it suitable for critical infrastructure protection.
Recommended
Motor Control
The AD7606BSTZ is used in motor control systems to simultaneously sample phase currents and voltages for field-oriented control (FOC). Its 8 channels can monitor three-phase currents, DC bus voltage, and additional sensors like temperature or encoder feedback. The simultaneous sampling ensures accurate phase alignment, which is essential for torque and speed control. The device's 200 kSPS sampling rate is sufficient for high-bandwidth current loops, and the integrated reference reduces external component count. The bipolar input range accommodates bidirectional current sensing with shunt resistors. The compact LQFP package fits space-constrained motor drives.
Recommended
Multi-Axis Vibration Analysis
The AD7606BSTZ is well-suited for multi-axis vibration analysis systems that require simultaneous sampling of accelerometer outputs. Its 8 channels can capture X, Y, and Z axes from multiple sensors, preserving phase relationships for modal analysis. The 16-bit resolution and 200 kSPS sampling rate capture high-frequency vibration components, while the integrated antialiasing filter prevents aliasing. The device's serial interface simplifies connection to a host processor, and the internal reference reduces noise. The industrial temperature range allows deployment in harsh environments such as turbine monitoring and structural health monitoring.
Recommended
Data Acquisition Systems
The AD7606BSTZ is a complete data acquisition system (DAS) that integrates the entire analog front end, making it ideal for general-purpose DAQ applications. It provides 8 simultaneous sampling channels with 16-bit resolution and 200 kSPS throughput, sufficient for most industrial and laboratory measurements. The device includes a 2.5V reference, antialiasing filters, and clamp protection, reducing external components and design complexity. The flexible digital interface (parallel, serial, SPI) allows easy integration with various host controllers. The compact LQFP package and wide temperature range make it suitable for portable and embedded DAQ systems.
Recommended
Medical Monitoring
The AD7606BSTZ can be used in medical monitoring equipment such as patient monitors and diagnostic devices that require simultaneous sampling of multiple physiological signals. Its 8 channels can acquire ECG, EEG, and other biosignals with 16-bit resolution, ensuring accurate waveform capture. The device's low noise and integrated antialiasing filter are beneficial for weak signal detection. The bipolar input range accommodates both positive and negative signal excursions. The industrial temperature range and high reliability make it suitable for medical devices that must operate continuously. The serial interface simplifies isolation barriers for patient safety.

- Wider temperature range (vs AD7606C-16BSTZ)
Design Notes
Decouple AVCC and DVCC with 10 Β΅F and 0.1 Β΅F capacitors placed as close to the pins as possible. Use a low-impedance ground plane to minimize noise. The VDRIVE pin should be connected to the logic supply of the host interface (2.3V to 5V) to ensure proper logic levels.
Route analog inputs away from digital traces to avoid coupling. Use a solid ground plane under the ADC. For best performance, keep the analog input traces short and shielded. The REFIN/REFOUT pin should have a 1 Β΅F decoupling capacitor to ground.
Ensure the CONVST A and CONVST B pins are driven simultaneously for true simultaneous sampling. If using the parallel interface, ensure the PAR/SER/BYTE pin is set correctly. Do not exceed the absolute maximum ratings on the analog inputs; the internal clamp protection handles transients but sustained overvoltage can damage the device.
