AD7147WPACPZ-1500R

Overview

The AD7147WPACPZ-1500R is an automotive-grade CapTouch programmable controller for single-electrode capacitance sensors. It integrates a 16-bit, 250 kHz sigma-delta converter with 13 sensor inputs (CIN0–CIN12). The device operates on a 2.6 V to 3.6 V supply and features an SPI-compatible serial interface. Key specifications include a typical update rate of 9 ms for all inputs, femtofarad resolution, and low power consumption of 21.5 μA in idle mode. It includes on-chip calibration logic and adaptive thresholding to compensate for environmental changes.

Feature Summary

13-channel capacitance-to-digital conversion with 16-bit resolution
Automotive qualified (AEC-Q100) with -40°C to +105°C operating range
SPI-compatible serial interface with separate VDRIVE level
On-chip automatic calibration and adaptive threshold logic

Applications

Automotive touch interfaces
Smart handheld devices
Personal music and multimedia players

Procurement Notes

Verify the specific suffix '1500R' against official Analog Devices documentation to confirm reel quantity and packaging details. Ensure the automotive grade qualification aligns with system requirements. Confirm pin compatibility with standard AD7147 designs if replacing non-automotive variants.

Selection Notes

Select this part for applications requiring AEC-Q100 certification and SPI connectivity. The AD7147 supports up to 13 single-electrode sensors without external RC components. Compare with the AD7147-1 if I2C interface is preferred instead of SPI.

Part Context

This component belongs to the AD7147 family of CapTouch controllers. It shares the same core functionality as the commercial AD7147ACPZ but is manufactured to meet automotive reliability standards. The WPACPZ designation indicates the wide temperature package variant.

Replacement Considerations

The AD7147ACPZ-RL is a commercial equivalent with identical electrical performance but lacks automotive qualification. Verify that the lower temperature range (-40°C to +85°C) of the commercial part meets the application's thermal requirements.
