DESCRIPTION
FSEL
1
Crystal frequency select input. This pin is used to select the master crystal frequency as
follows: FSEL = HIGH = 256f
s
; FSEL = LOW = 512f
s
; if unconnected the pin will default
HIGH.
test input 1; this pin should be left open-circuit
test input 2; this pin should be left open-circuit
supply ground for the digital section
supply voltage for the digital section (+5 V)
crystal oscillator input
crystal oscillator output
system clock output
output clock at a frequency half the system clock frequency
serial interface clock input
serial interface clock output
serial interface data output
serial interface word select input
serial interface word select output
input for selecting between the internally generated 1-bit code (DSEL = HIGH) or an
externally generated 1-bit code (DSEL = LOW); if unconnected this pin defaults HIGH
1-bit code clock output
1-bit code input/output (right channel)
1-bit code input/output (left channel)
supply ground for the analog timing section
supply voltage for the analog timing section (+5 V)
voltage reference generator for the right channel analog section
output of right channel buffer operational amplifier ‘B’
positive input to right channel Sigma-Delta modulator
negative input to right channel Sigma-Delta modulator
output of right channel buffer operational amplifier ‘A’
input of right channel buffer operational amplifier ‘A’
negative voltage reference level input for the DACs
current reference output
positive voltage reference level input for the DACs
input of left channel buffer operational amplifier ‘A’
output of left channel buffer operational amplifier ‘A’
negative input to left channel Sigma-Delta modulator
positive input to left channel Sigma-Delta modulator
output of left channel buffer operational amplifier ‘B’
voltage reference generator for the left channel analog section
supply voltage for the analog section (+5 V)
supply ground for the analog section
