LTC1594L/LTC1598L
U U U PIN FUNCTIONS VCC (Pin 15):
Power Supply Voltage. This pin provides
VCC (Pin 19):
Power Supply Voltage. This pin should be power to the A/D Converter. It must be bypassed directly tied to Pin 15. to the analog ground plane.
CH0 (Pin 20):
Analog Multiplexer Input.
VREF (Pin 16):
Reference Input. The reference input
CH1 (Pin 21):
Analog Multiplexer Input. defines the span of the ADC.
CH2 (Pin 22):
Analog Multiplexer Input.
ADCIN (Pin 17):
ADC Input. This input is the positive analog input to the ADC. Connect this pin to MUXOUT for
CH3 (Pin 23):
Analog Multiplexer Input. normal operation.
CH4 (Pin 24):
Analog Multiplexer Input.
MUXOUT (Pin 18):
MUX Output. This pin is the output of the multiplexer. Tie to ADCIN for normal operation.
