0 V to 250 mV in the presence of common-mode voltages from 0 V to 36 V. The INA300EVM allows for easy user configuration of the INA300 device by using jumpers. The following features can be programmed in this manner: •... -
Page 3: Related Documentation From Texas Instruments
The following document provides information regarding Texas Instruments integrated circuits used in the assembly of the INA300EVM. This document is available from the TI web site under literature number SBOS613. 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 4: Connecting The Ina300Evm With Voltage Sources
Overview www.ti.com Configuring and Using the INA300EVM The INA300EVM is fully assembled, factory tested, and ready to use. For fast evaluation of the INA300 device, the INA300EVM can be configured as shown in Figure = +2.7 V to 5.5 V = 0.3 V to 36 V... -
Page 5: Connecting The Ina300Evm As A High-Side Current Comparator
These connections are established by using a shunt resistor to create the shunt voltage at the input. Configuring the differential input to the INA300EVM as a shunt resistor in series with a load may be more suitable in some evaluations than configuring the differential input to the INA300EVM as a voltage source;... - Page 6 The INA300 is a voltage comparator. The comparator threshold voltage is set by the value of the voltage applied to the Limit pin on the INA300. On the INA300EVM, a resistor is connected to the output of the Limit pin and ground. The output of the Limit pin is a constant current sourced from an internal, precision, band-gap voltage reference.

Page 7: Enable/Disable Jumper Location
Connecting the jumper to ground disables the INA300; connecting the jumper to VDD enables the INA300. The INA300EVM comes enabled from the factory by default. If the jumper is left floating or removed, the INA300 defaults to the enabled state. Refer to... -
Page 8: Transparent/Latch Jumper
INA300 in transparent mode; connecting the jumper to VDD configures the INA300 in latch mode. The INA300EVM comes configured in transparent mode from the factory by default. If the jumper is left floating or removed, the INA300 defaults to the transparent state. Refer to... -
Page 9: Delay Jumper Location
VDD configures the INA300 for a 100-µs delay. If the jumper is left floating or removed, the INA300 defaults to a 10-µs delay. The INA300EVM comes configured for a 100-µs delay from the factory by default. Refer to Figure 9 for detailed operation of the delay jumper. -
Page 10: Hysteresis Jumper Location
VDD configures the INA300 for a 10-mV hysteresis. If the jumper is left floating or removed, the INA300 defaults to a 2-mV hysteresis. The INA300EVM comes configured for a 5-mV hysteresis from the factory by default. Refer to... -
Page 11: Limit Jumper Location
Limit Jumper The INA300EVM uses a jumper-configurable connection that uses either a resistor or an external voltage source, such as a DAC (not included on the INA300EVM), as the input to the limit pin. Figure 12 shows the location of the limit jumper (J5). The INA300EVM PCB is clearly marked for easy configuration. The middle pin of the limit jumper is connected directly to the INA300 limit pin. -
Page 12: Low-Pass, Passive Input Filter
The INA300EVM is designed to accommodate a user-configurable, first-order, low-pass, passive input filter. Figure 14 shows the location and construction of the filter. The INA300EVM comes populated with two 0-Ω resistors (R4 and R5). However, the filter capacitor is not installed. INA300 Figure 14. -
