What are the key features of AD7865YSZ-2?

  • 4 simultaneous-sampling input channels with 14-bit resolution capture transient events across all channels at the same instant, eliminating phase error in multi-axis systems
  • 2.4 µs maximum conversion time per channel supports throughput rates up to 416 kSPS for high-speed data-acquisition loops
  • Parallel interface with full 14-bit data bus simplifies direct connection to DSPs and FPGAs without serial protocol overhead
  • ±5 V bipolar analog input range accepts differential signals from ±2 V or ±5 V full-scale, configurable per channel
  • 44-pin MQFP package with 30 specified electrical parameters enables compact multi-channel board designs

What is AD7865YSZ-2 used for?

The AD7865YSZ-2 is used in industrial motor-drive and servo-control systems where simultaneous sampling of 4 current or voltage feedback channels at 14-bit resolution is required to avoid phase mismatches that degrade torque control. Medical imaging and ultrasound equipment benefit from its high linearity (0.0122 % max error) and fast 2.4 µs conversion when capturing real-time signals across multiple transducer elements. Power-grid monitoring and power-quality analyzers also rely on the device to sample voltage and current waveforms simultaneously for accurate harmonic analysis.

Frequently Asked Questions

How does simultaneous sampling on the AD7865YSZ-2 benefit motor-control designs compared to multiplexed ADCs?

By sampling all 4 channels at the same instant, the AD7865YSZ-2 eliminates the phase skew that multiplexed ADCs introduce between successive conversions. In a 3-phase motor-control loop running at 10 kHz, even a 1 µs skew between current samples can distort the d-q transform; simultaneous 14-bit captures remove this error source entirely, improving torque accuracy.

What is the maximum conversion time and effective throughput rate for the AD7865YSZ-2?

The AD7865YSZ-2 completes one full 4-channel simultaneous conversion in a maximum of 2.4 µs, yielding a maximum throughput of approximately 416 kSPS per channel. This rate supports control-loop bandwidths up to around 40 kHz when using standard Nyquist margins, meeting the requirements of high-performance servo and power-conversion designs.

What analog input voltage range does the AD7865YSZ-2 accept, and how does that affect signal-conditioning circuit design?

The AD7865YSZ-2 accepts analog inputs up to ±5 V full-scale on each of its 4 channels. Designers targeting ±2 V signal sources can use a simple resistor-divider or fixed-gain instrumentation amplifier to scale signals to the full ±5 V range, maximising the 14-bit dynamic range and keeping noise contribution below 1 LSB at the 0.0122 % linearity specification.

Which package does the AD7865YSZ-2 come in, and what should designers consider for PCB layout?

The device is housed in a 44-pin MQFP (metric quad flat pack) package. The MQFP footprint requires 0.8 mm pitch pad spacing, so designers should use 0.3 mm to 0.4 mm solder mask openings and maintain analog and digital ground planes separated under the device to limit switching noise coupling into the 14-bit analog inputs.

Is the AD7865YSZ-2 RoHS-compliant, and what are the key procurement considerations?

The AD7865YSZ-2 carries a JESD-609 code of e3, indicating it is not RoHS-compliant (leaded finish). Its YTEOL of 0 signals limited remaining life-cycle inventory. Designers starting new PCB designs should evaluate the RoHS-compliant variant or the newer AD7864 family; existing designs using leaded solder processes can source remaining stock from authorised distributors with worldwide shipping.
