User's Guide SBOU086 – August 2011 INA216EVM This user’s guide describes the characteristics, operation, and use of the INA216EVM evaluation module (EVM). This EVM is designed to evaluate the performance of the INA216 family of voltage output current shunt monitors. This EVM has a flexible configuration, allowing for user evaluation suitable to a variety of applications.

www.ti.com Introduction and Overview 1 Introduction and Overview 1.1 INA216 The INA216 devices are voltage output, high-side measurement, unidirectional, zero-drift current shunt monitors. This family of devices has gains that range from 25V/V to 200V/V. The voltage developed across the device inputs is amplified by the corresponding gain of the chosen device and is presented at the output pin. The INA216 devices can sense voltage drops across shunts at common-mode voltages between 1.8V to 5.5V.
PAGE 3
www.ti.com 1.3 Introduction and Overview Hardware Included The INA216 family of devices are available in a WCSP with each of the available gain versions provided in all INA216EVMs delivered, as Figure 1 shows. Figure 1.
PAGE 4
www.ti.com Quick Start Setup and Use 2 Quick Start Setup and Use Follow these procedures to set up and use the INA216EVM. Step 1. Insert the device board to be evaluated into the U1 location. The U1 location allows the user to interchange device boards to evaluate the impact of implementing various gains in the design. Step 2. Connect the INA216 input pins to both the common-mode source as well as the load.

www.ti.com 2.2 Quick Start Setup and Use Measurement Without Shunt This connection method allows the user to either simulate the voltage developed across a sense resistor based on a given set of system conditions, or to connect the INA216EVM remotely to an existing shunt already included in an example application. Figure 3 illustrates a measurement configuration without a shunt. To configure a measurement evaluation without a shunt, follow these procedures. 1.

www.ti.com INA216EVM Circuit 3 INA216EVM Circuit This section summarizes the INA216EVM components. 3.1 R1 R1 can be used for shunt resistors that have a package that is not easily adaptable to a standard, two-terminal, through-hole footprint or to a 0603 through 1206 surface-mount footprint. Specifically, this component location was added to allow for the use of TO-126, TO-220, TO-247, and four-terminal inline radial packages such as the CS3 series of shunts from Ohmite.

www.ti.com INA216EVM Circuit 3.2 R2 R2 is intended to handle two- and four-terminal radial packages (as Figure 8 illustrates) as well as surface-mount packages that range in size from 0603 to 1206. Figure 8. Radial Package in R2 3.3 R3, R4, C1 R3 and R4 are factory-installed 0Ω resistors. These resistors, in combination with C1, form an input filter. These locations allow for through-hole and surface-mount packages that range in size from 0603 to 1206.

www.ti.com 3.5 INA216EVM Circuit U1 U1 is the location for the test device, as shown in Figure 9. Four device boards are supplied with the INA216EVM board; each device board is populated with one of the available device gains. This interchangeable option allow users to test the devices and determine the gain setting that is best suited for a given application. Figure 10 shows the U1 slot populated with a DIP board device as an example. Figure 9. U1 Footprint Figure 10.

www.ti.com INA216EVM Schematic and PCB Layout There are several factors to consider when selecting the appropriate device: • The INA216 devices are identical with the exception of different gain settings. • The limiting factor that requires attention to be given to device selection is the output voltage. • The output voltage has a restriction: it must remain within the range of 2mV above ground to 300mV below the supply voltage.
