Both use the same 24-LFCSP package and footprint, making the higher-resolution AD7383-4 a drop-in hardware replacement. However, register settings and SPI data formatting differ because of the resolution increase, so firmware must be updated when swapping between the two parts.

AD7384-4BCPZ vs AD7380-4BCPZ - which is better for motor control?

For motor control, the 14-bit AD7384-4BCPZ is often the better choice because it provides sufficient resolution for current and voltage sensing while producing less data on the SPI bus than the 16-bit AD7380-4BCPZ. Both parts support quad simultaneous sampling, which is essential for capturing phase currents at the same instant. Choose AD7380-4 only if your algorithm requires the extra 16-bit resolution.

When should I choose AD7384-4BCPZ over AD7383-4BCPZ?

Choose AD7384-4BCPZ when 14-bit resolution meets your accuracy target and you want to minimize data throughput, SPI bandwidth, and cost. Choose AD7383-4BCPZ when you need 16-bit resolution for higher dynamic range or lower noise performance. Both parts share the same quad simultaneous architecture, oversampling block, and 24-LFCSP footprint, so the PCB layout does not need to change.

Is AD7384-4BCPZ suitable for power quality monitoring?

Yes, the AD7384-4BCPZ is suitable for power quality monitoring because its four simultaneously sampled channels capture all phase voltages and currents at the same instant, avoiding phase measurement errors. The 4 MSPS rate and on-chip oversampling also support harmonic analysis and waveform capture. This makes it a strong fit for three-phase energy metering and protective relay designs that need precise vector measurements.

What is the best drop-in replacement for AD7384-4BCPZ?

Key Differentiators

Quad simultaneous sampling with 14-bit resolution (vs AD7383-4BCPZ)
On-chip oversampling improves effective resolution by up to 2 bits (vs AD7389-4BCPZ)
Same board footprint across the quad family (vs AD7381-4BCPZ)

Design Notes

Place a 100 nF ceramic capacitor close to each supply pin (VDD and VDRIVE) and a 10 uF bulk capacitor near the ADC. The reference pin should be bypassed with a 1 uF low-ESR capacitor, and this capacitor should be placed directly between REF and REFGND. The internal reference buffer requires a low-impedance ground connection to maintain accuracy at 4 MSPS and to support the on-chip oversampling engine.

Use a continuous ground plane under the 24-LFCSP package and solder the exposed thermal pad to the PCB ground plane. Keep analog input traces short and shielded from digital SPI lines. Separate analog and digital ground returns at the ADC, joining them at the thermal pad. This layout minimizes coupling of SPI clock noise into the pseudo-differential inputs and preserves SNR.

Verify the pseudo-differential input common-mode range before connecting the ADC. The input span is defined relative to REF; exceeding the common-mode range causes linearity errors. Also confirm SPI mode and timing in the AD7384-4 datasheet, especially CS setup/hold time when operating at 4 MSPS. Do not leave the reference pin un-bypassed, as this degrades undersampled measurements.
