2.2 INA260EVM PCB Description

Figure 2-3 depicts a block diagram of the INA260EVM PCB highlighting the power supplies, analog inputs, and digital I/O signals.

The EVM PCB requires minimal instrumentation to be operated. In fact, the only pieces of required equipment not included in the kit are a ( Windows® 7) computer and an input current source. All other inputs are supplied by the SM-USB-DIG board, via the 10-pin connector socket, J4. Table 2-1 lists the pinout for J4.

PIN ON J4

SIGNAL

DESCRIPTION
10 I2C_SCL I2C clock signal (SCL)
9 CTRL/MEAS4 GPIO: control output or measure input
8 I2C_SDA1 I2C data signal (SDA)
7 CTRL/MEAS5 GPIO: control output or measure input
6 SPI_DOUT1 SPI data output (MOSI)
5 VDUT Switchable DUT power supply: 3.3 V, 5 V, Hi-Z (disconnected)(1)
4 SPI_CLK SPI clock signal (SCLK)
3 GND Power return (GND)
2 SPI_CS1 SPI chip-select signal ( CS)
1 SPI_DIN1 SPI data input (MISO)
(1) When VDUT is Hi-Z, all digital I/Os are Hi-Z as well.
