3.3.3 Analog Front End
The Analog Front End sub-panel configures the amplifier, modulator and test DAC pin options. Pin op-
tions are controlled through the GPIO outputs of the digital filter.
Any changes made under this sub-panel will not be applied to the target board until the Configure button
is pushed. The Configure button writes the new configuration to the target board and then enables the
data Capture button.
Control Description
Amp Mux Selects the input source for the CS3301A/02A amplifiers. An internal termination,
external INA inputs or external INB inputs can be selected.
DAC Mode Selects the operational mode of the CS5373A test DAC. The test DAC operational
modes are AC dual output (OUT&BUF), AC precision output (OUT only), AC buffered
output (BUF only), DC common mode output (DC Common), DC differential output
(DC Diff), or AC common mode output (AC Common). The test DAC can also be
powered down (PWDN) when not in use to save power.
Gain Sets the amplifier gain range and test DAC attenuation. Amplifier gain and DAC
attenuation settings of 1x, 2x, 4x, 8x, 16x, 32x, or 64x can be selected and are con-
trolled together.
Pwdn Disabled for CDB5378. PWDN routes to DIP switch S5.
