Overview

The Digilent PmodDPG1 (Revision A) is a differential gauge pressure module. With NXP's MP3V5010DP

piezoresistive transducer and Texas Instrument's ADCS7476 12-bit Analog-to-Digital Converter, you can detect

when a change in pressure between the two ports occurs and send digital information to your system board.

1 Functional Description

The PmodDPG1 is designed to detect a gauge pressure ranging from 0 kPa to 10 kPa with a piezoresistive

transducer and use an embedded 12-bit ADC to provide the user with a serial stream of data representative of the

measured pressure.

The PmodDPG1.

 Differential gauge pressure transducer

 12-bit ADC

 0 to 10 kPa differential pressure range

 Temperature compensated and calibrated

 6-pin Pmod connector with SPI interface

 Follows Digilent Pmod Interface
