Programmable Pre-Amplifier
Finally, the ADC presents a 14-bit, two’s complement digital output. A 14-bit, two’s
complement number represents values between -2 13 and 2 13 -1. Therefore, the quantity is
scaled by 8192, or 2 13 .
See “Programmable Pre-Amplifier” to control the GAIN settings on the programmable
pre-amplifier.
The reference design files provide more information on converting the voltage applied on
VINA or VINB to a digital representation (see “Related Resources,” page 77 ).
Programmable Pre-Amplifier
The LTC6912-1 provides two independent, inverting amplifiers with programmable gain.
The purpose of the amplifier is to scale the incoming voltage on VINA or VINB so that it
maximizes the conversion range of the DAC, namely 1.65 ± 1.25V.
Interface
Table 9-1 lists the interface signals between the FPGA and the amplifier. The SPI_MOSI
and SPI_SCK signals are shared with other devices on the SPI bus. The AMP_CS signal is
the active-Low slave select input to the amplifier.

Programmable Gain
Each analog channel has an associated programmable gain amplifier (see Figure 9-2 ).
Analog signals presented on the VINA or VINB inputs on the J7 header are amplified
relative to 1.65V. The 1.65V reference is generated using a voltage divider of the 3.3V
voltage supply.
The gain of each amplifier is programmable from -1 to -100, as shown in Table 9-2 .
