VCC
Power-Supply Input. Bypass VCC to GND with 1FF and 0.01FF capacitors in parallel as close to the
device as possible; recommended for each VCC pin.
2
OAMPA
OUTAP/OUTAM Output Level Selection. Drive OAMPA high for low output amplitude. Drive OAMPA
low or leave unconnected for high output amplitude. See the Electrical Characteristics table.
OAMPA is internally pulled down by a 330kI (typ) resistor.
3
OAMPB
OUTBP/OUTBM Output Level Selection. Drive OAMPB high for low output amplitude. Drive OAMPB
low or leave unconnected for high output amplitude. See the Electrical Characteristics table.
OAMPB is internally pulled down by a 330kI (typ) resistor.

SEL1
Channel 1 Active-Output Selection Input. Drive SEL1 low or leave unconnected to activate A
outputs. Drive SEL1 high to activate B outputs. SEL1 is internally pulled down by a 330kI (typ)
resistor.
9
SEL2
Channel 2 Active-Input Selection Input. Drive SEL2 low or leave unconnected to activate A inputs.
Drive SEL2 high to activate B inputs. SEL2 is internally pulled down by a 330kI (typ) resistor.
10
EN
Enable Input. Drive EN low or leave unconnected for reduced power standby mode. Drive EN high
for normal operation. See Table 1. EN is internally pulled down by a 330kI (typ) resistor.
