1067BX–BDC–12/11
The ADA4960 is used in DC configuration with output common mode driven by ADC
QUAD 10-bit. The input is biased at 2.5V since this is a requirement for best perfor-
mance from the amplifier, this should be taken into account when using this input.
Note: be careful that if a DC voltage is added after the RF generator output that this will not
damage the generator.
The ADA4960 is used in AC configuration in channel C.
3.1.2 Analog Input
Channel B
The Analog input channel B uses an RF Transformer from MACOM ref: ETC1-1-13 /
MABA-007159
Figure 3-3. Channel B : Schematic
3.1.3 Analog Input
Channel C
The Analog input channel C uses a differential amplifier (ADC driver) from Analog
Devices: ref: ADA4960-1.
Figure 3-4. Channel C : Schematic
The ADA4960-1 is used in AC configuration with output common mode driven by Quad
10-bit ADC.
