Product Overview

AD7616BSTZ is a high-performance 16-bit data acquisition system (DAS) launched by ADI, integrated with dual simultaneous sampling ADCs and supporting 16-channel signal acquisition. It is the core model of the same series as AD7616BSTZT . Powered by a single 5V supply, this device can handle true bipolar input signals of ±10V, ±5V, and ±2.5V, with each channel pair achieving a throughput rate of up to 1 MSPS. It delivers 90.5 dB SNR at 1 MSPS sampling rate, and the SNR increases to 92 dB when the oversampling rate (OSR) is set to 2 . Integrating analog input clamp protection, 1 MΩ high input impedance, and flexible interfaces, it eliminates the need for external driver op-amps and bipolar power supplies, providing an all-in-one solution for high-precision data acquisition scenarios.

Technical Specifications

Typical Applications

• Power Line Monitoring: With 16-channel simultaneous sampling capability and ±10V wide input range, AD7616BSTZ can accurately collect voltage and current signals of multi-phase power lines. The 90.5 dB high SNR ensures the accuracy of harmonic analysis, and the ±21V voltage protection adapts to grid fluctuation scenarios, making it an ideal ADC solution for power monitoring systems .
• Multiphase Motor Control: Supporting dual simultaneous sampling and 1 MSPS high throughput rate, it can real-time capture current and voltage signals of each motor phase. The ±1 LSB INL accuracy guarantees the precise execution of control algorithms, and the single-power design simplifies the circuit layout of motor controllers, with DSP interface compatibility facilitating system integration .
• Protective Relays: 8 kV ESD protection and ±21V input clamp protection enhance the anti-interference capability of the equipment. The 1 MΩ high input impedance reduces signal attenuation, and the 92 dB SNR (oversampling mode) ensures accurate fault signal identification. The fast response characteristic meets the millisecond-level protection action requirements of relays .
• Instrumentation: 16-bit high resolution and -103 dB low THD performance make it suitable for precision instruments such as oscilloscopes and signal analyzers. The flexible SPI/QSPI interfaces can connect to microcontrollers, and the on-chip reference voltage source reduces the cost of external components. The -40°C~125°C operating temperature range adapts to both laboratory and industrial field environments .
• Data Acquisition Systems (DAS): As a cost-effective model in the same series as AD7616BSTZT, the 16-channel integrated design reduces the number of components. The simultaneous sampling function ensures the time consistency of multi-sensor data, and the 350mW low power consumption adapts to portable DAS devices, fully meeting the high-precision and integration requirements of industrial data acquisition .
