- Page 1 SBOU154 – November 2015 INA301EVM User's Guide This user’s guide describes the characteristics, operation, and use of the INA301EVM evaluation module. This guide discusses how to set up and configure the hardware. Throughout this document, the terms evaluation board, evaluation module, and EVM are synonymous with the INA301EVM. This document also includes an electrical schematic, printed circuit board (PCB) layout drawings, and a parts list for the EVM.
- Page 2 The following documents provide information regarding Texas Instruments' integrated circuits used in the assembly of the INA301EVM. This user's guide is available from the TI web site under literature number SBOU154. Any letter appended to the literature number corresponds to the document revision that is current at the time of the writing of this document.
- Page 3 INA301EVM Hardware The INA301EVM requires a 2.7-V to 5.5-V power supply. Connect the VIN+ and VIN– pins across an external shunt resistor in series with a 0-V to 36-V supply to determine the current flowing through that resistor. Use a voltmeter on the OUT pin to measure the voltage output and on the ALERT pin to determine the comparator output.
- Page 4 Quick-Start Setup and Use Follow these procedures to set up and use the INA301EVM: 1. Connect an external dc supply voltage between 2.7 V and 5.5 V to the J3-1 terminal. 2. Connect the desired input to the J4 terminal. This input is either a remote shunt resistor or a differential voltage source with a common-mode voltage of 0 V to 36 V referenced to GND.
- Page 5 VS. C2 along with R4 and R5 creates an optional filter for the VIN+ and VIN– inputs. R6 is an optional shunt resistor for the INA input. Figure 2. INA301EVM Test Board Schematic SBOU154 – November 2015 INA301EVM User's Guide Submit Documentation Feedback Copyright ©...
