Description
Analog Output. Negative power supply converter output
and reservoir capacitor connection. This output can be
used to provide negative bias to other devices in the system.
Analog Output. Integrator capacitor connection and integrator
output.
Analog Input. Auto Zero capacitor connection.
Analog Output. Integrator capacitor connection and voltage
buffer output.
Analog Input. This pin is ground for all of the analog switches
in the A/D converter. It is grounded for most applications.
ACOM and the input common pin (VI–N or Chx–) should be
within the common mode range, CMR.
Analog Input. Reference cap negative connection.
Analog Input. Reference cap positive connection.
Analog Input. External voltage reference negative connection.
Analog Input. External voltage reference positive connection.
Analog Input. Multiplexer channel 4 negative differential
analog input.
Analog Input. Multiplexer channel 3 negative differential
analog input.
Analog Input. Multiplexer channel 2 negative differential
analog input.
Analog Input. Multiplexer channel 1 negative differential
analog input.
Analog Input. Multiplexer channel 4 positive differential
analog input.
Analog Input. Multiplexer channel 3 positive differential
analog input.
Analog Input. Multiplexer channel 2 positive differential
analog input.
Analog Input. Multiplexer channel 1 positive differential
analog input.
Analog Input. Negative differential analog voltage input.
Analog Input. Positive differential analog voltage input.
Analog Input. Ground connection for serial port circuit.
Logic Level Input. Multiplexer address MSB.
Logic Level Input. Multiplexer address LSB.
Analog Input. Timebase for state machine. This pin connects
to one side of an AT-cut crystal having an effective series
resistance of 100Ω (typ) and a parallel capacitance of 20pF
If an external frequency source is used to clock the TC530/534,
this pin must be left floating.
