17
MUXOUT
Negative Multiplexer Output. This pin allows access to the on-chip track-and-hold. The voltage applied to this
pin is still a high voltage signal when the AD7329 is in differential mode. When the AD7329 is in single-ended
mode, this signal is AGND, and MUXOUT can be connected directly to the ADCIN pin. When the AD7329 is in
pseudo differential mode, a small dc voltage appears at this pin, and this pin should be tied to the ADCIN pin.
18
ADCIN
Negative ADC Input. This pin allows access to the track-and-hold. When the AD7329 is in single-ended mode,
this pin can be tied to MUXOUT, which is connected to AGND. When the AD7329 is in pseudo differential
mode, this pin should be connected to MUXOUT. When the AD7329 is in true differential mode, the voltage
applied to this pin is a high voltage signal (±10 V, ±5 V, ±2.5 V, or 0 V to +10 V).

VIN0 to VIN7
Analog Input 0 Through Analog Input 7. The analog inputs are multiplexed into the on-chip track-and-hold.
The analog input channel for conversion is selected by programming the channel address bits, ADD2
through ADD0, in the control register. The inputs can be configured as eight single-ended inputs, four true
differential input pairs, four pseudo differential inputs, or seven pseudo differential inputs. The configuration
of the analog inputs is selected by programming the mode bits, Mode 1 and Mode 0, in the control register.
The input range on each input channel is controlled by programming the range registers. Input ranges of
±10 V, ±5 V, ±2.5 V, or 0 V to +10 V can be selected on each analog input channel (see the Range Registers
section). On power up, VIN0 is automatically selected and the voltage on this pin appears on MUXOUT+.
