PINTYPE(1)DESCRIPTION
NAMENO.
A13I/OInput/Output A port for Channel 1
A24I/OInput/Output A port for Channel 2
B16I/OInput/Output B port for Channel 1
B25I/OInput/Output B port for Channel 2
EN8II/O enable input; see Figure 9-1 for typical setup. Should be tied directly to Vref_B to be enabled or pulled LOW to disable all I/O pins.
GND1—Ground
Vref_A2—A side reference supply voltage; see Section 9 for setup and supply voltage range.
Vref_B7—B side reference supply voltage. Must be connected to supply through 200 kΩ; see Section 9 for setup and supply voltage range.
(1) I = input, O = output
