DESCRIPTION
0 V digital supply
5 V digital supply for both channels
serial one-bit data input for the right channel
pin not connected; should preferably be connected to digital ground
clock input for the right channel
5 V digital supply for the right channel; this voltage determines the internal logic HIGH level
in the right channel
−3.5 V digital supply for the right channel; this voltage determines the internal logic LOW
level in the right channel
−4 V reference voltage for the right channel switched capacitor DAC
0 V reference voltage for the right channel switched capacitor DAC; this pin should be
connected to analog ground
output from the right negative switched capacitor DAC; feedback connection for the right
negative operational amplifier
output from the right positive switched capacitor DAC; feedback connection for the right
positive operational amplifier
0 V reference voltage for both right channel operational amplifiers
pin not connected; should preferably be connected to analog ground
+ output of the switched capacitor operational amplifier
− output of the switched capacitor operational amplifier
−5 V analog supply
5 V analog supply
− output of the switched capacitor operational amplifier
+ output of the switched capacitor operational amplifier
pin not connected; should preferably be connected to analog ground
0 V reference voltage for both left channel operational amplifiers
output from the left positive switched capacitor DAC; feedback connection for the left
positive operational amplifier
output from the left negative switched capacitor DAC; feedback connection for left negative
operational amplifier
0 V reference voltage for the left channel switched capacitor DAC; this pin should be
connected to analog ground
−4 V reference voltage for the left channel switched capacitor DAC
−3.5 V digital supply for the left channel; this voltage determines the internal logic LOW level
in the left channel
5 V digital supply for the left channel; this voltage determines the internal logic HIGH level in
the left channel
