noted. The UNR-1.8/2-D5 and D5SM models require an external 15kΩ pull-up resistor between
+Input and On/Off Control for normal operation. See On/Off Control for details.
models are specified with an external 22µF input capacitor. All other models are specified with
no external I/O capacitors. Output noise on the D12 models can be reduced significantly with
the addition of external output capacitors. See I/O Filtering.
