1 Introduction and Overview
This document provides the information needed to set up and operate the PGA309EVM-USB evaluation
module, a test platform for the
PGA309 programmable sensor conditioner. For a more detailed description
of the PGA309, refer to the product data sheet ( SBOS292 ) available from the Texas Instruments web site
at http://www.ti.com . Additional support documents are listed in the section of this guide entitled Related
Documentation from Texas Instruments .
The PGA309EVM-USB is an evaluation module that is used to fully evaluate the PGA309. The PGA309 is
an integrated circuit that provides temperature compensation and linearization for bridge sensors. The
PGA309EVM-USB consists of two PCBs. One board (the USB-DAQ-Platform) generates the digital
signals required to communicate with the PGA309. The other board (the PGA309_Test_Board) contains
the PGA309 device, as well as support and configuration circuitry.
Throughout this document, the abbreviation EVM and the term evaluation module are synonymous with
the PGA309EVM-USB.
