Typical Applications
AD4853BCPZ is suitable for 6 applications: Industrial Process Control, Motor Control, Power Quality Monitoring, Medical Imaging, Test and Measurement, Vibration Analysis.
Industrial Process Control
The AD4853BCPZ provides 4-channel simultaneous sampling with 16-bit resolution and 1MSPS throughput, ideal for multi-loop process control systems. Its buffered inputs handle sensor signals directly, while the wide common-mode range accommodates various transducer outputs. The integrated reference simplifies design, and the SPI/LVDS interface ensures reliable data transfer to PLCs or MCUs. With 57mW per channel power, it suits distributed control nodes. The -40Β°C to +125Β°C range ensures operation in harsh industrial environments.
Recommended
Motor Control
Simultaneous sampling of phase currents and voltages is critical for field-oriented control (FOC) of motors. The AD4853BCPZ captures all four channels concurrently, ensuring phase-aligned data for accurate torque and speed estimation. Its 1MSPS per channel rate supports high-bandwidth control loops, while the buffered inputs eliminate the need for external op-amps. The integrated reference and decoupling capacitors reduce BOM count. The device's low power and small BGA package make it suitable for compact servo drives.
Recommended
Power Quality Monitoring
For power quality analyzers, the AD4853BCPZ's 4-channel simultaneous sampling captures voltage and current waveforms from three phases plus neutral. Its 16-bit resolution and 94.6dB SNR enable accurate harmonic analysis up to the Nyquist frequency. The wide common-mode input range allows direct connection to potential transformers and current transformers. The integrated reference ensures stable measurements over temperature. The SPI/LVDS interface supports high-speed data streaming to DSPs or FPGAs for real-time analysis.
Recommended
Medical Imaging
In ultrasound and MRI systems, the AD4853BCPZ provides high-resolution, simultaneous sampling of multiple transducer elements. Its 16-bit resolution and low input leakage (Β±75pA) preserve weak signals from sensors. The buffered inputs simplify interfacing to piezoelectric transducers without external buffers. The 1MSPS throughput supports real-time imaging, while the small BGA package saves board space in portable devices. The device's low power dissipation is beneficial for battery-operated equipment.
Recommended
Test and Measurement
The AD4853BCPZ is ideal for multi-channel data acquisition in test equipment such as oscilloscopes and data loggers. Its simultaneous sampling ensures accurate time alignment between channels, crucial for phase measurements. The 16-bit resolution and 1MSPS rate provide high dynamic range for capturing transient signals. The integrated reference and decoupling capacitors reduce external component count, simplifying calibration. The SPI/LVDS interface allows easy integration with FPGAs or high-speed MCUs for data processing.
Recommended
Vibration Analysis
For condition monitoring, the AD4853BCPZ captures multi-axis vibration signals simultaneously, preserving phase relationships essential for modal analysis. Its 16-bit resolution and 94.6dB SNR detect small vibrations in the presence of large DC offsets. The buffered inputs connect directly to IEPE accelerometers with proper conditioning. The 1MSPS per channel rate supports high-frequency vibration analysis. The device's low power and small size enable embedding in wireless sensor nodes.

Design Notes
The AD4853BCPZ requires a clean analog supply (AVDD) from 4.75V to 5.25V. Use a low-noise LDO, such as the LT3045, to power AVDD and minimize noise coupling. The digital supply (DVDD) can be derived from the same rail with proper filtering. Place 0.1uF and 10uF decoupling capacitors close to each supply pin, as the device integrates internal decoupling but external caps are still recommended for optimal performance.
For the 64-ball BGA package, ensure adequate thermal vias under the exposed pad to dissipate heat. Route analog inputs away from digital traces to avoid crosstalk. Use a solid ground plane and split analog/digital grounds if necessary, but connect them at a single point. Follow the layout guidelines in the AD4853 datasheet for best SNR and INL performance.
Do not exceed the absolute maximum ratings for AVDD and DVDD. Ensure the reference output (REF) is properly bypassed with a 10uF capacitor to ground. When using LVDS interface, terminate the differential pairs with 100 ohm resistors. Avoid floating unused inputs; tie them to ground or a common-mode voltage. Verify the SPI timing parameters in the datasheet to ensure reliable communication.
