Table 5-1 Pin Functions
PIN TYPE(1) DESCRIPTION
NAME NO.
A1 3 I/O Input/Output A port for Channel 1
B1 4 I/O Input/Output B port for Channel 1
EN 6 I I/O enable input; see Section 9.2.1.2.1 for typical setup. Should be tied directly to Vref_B to be enabled or pulled LOW to disable all I/O pins.
GND 1 — Ground
Vref_A 2 — A side reference supply voltage; see Section 9 for setup and supply voltage range.
Vref_B 5 — B side reference supply voltage. Must be connected to supply through 200 kâ„Ĥ; see Section 9 for setup and supply voltage range.
(1) I = input, O = output
