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 CS3301/02 amplifiers. An internal termination, exter-

nal 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.
