The MAX1181 accepts differential or single-ended ana-
log input signals applied to Channels A or B. The EV kit
requires only single-ended analog input signals, with
an amplitude of less than 2V
During single-ended operation the signal is applied
directly to the ADC, while in differential mode, an on-
board transformer takes the single-ended analog input
and generates a differential analog signal at the ADCs
differential input pins. To evaluate single-ended signal
input, connect the input signal to the S/E_INA (Channel
A) or S/E_INB (Channel B) SMA connectors. To evalu-
ate differential signals, connect the input signal to the
D/E_INA (Channel A) or D/E_INB (Channel B) SMA con-
nectors. For single-ended or differential operation, see
Table 1 for jumper configuration.

Note: When a differential signal is applied to the ADC,
the positive and negative input pins of the ADC each
receive half of the input signal supplied at SMA
connector D/E_INA(D/E_INB) centered at the common
mode voltage of VADUT/2.
Output Enable/Power-Down/Sleep Modes
The MAX1181 EV kit also features jumpers that allow
the user to enable or disable certain functions or the
entire data converter. Jumper JU6 controls the Sleep
mode, jumper JU7 controls a full power-down mode,
and jumper JU8 controls the outputs enable/disable
mode. Operating the ADC in these modes supports the
reduction of the IC’s overall power consumption. Refer
to Table 2 to configure the board and operate the ADC
in these modes.
