Onboard Signal Conditioning
The multiplexer output of the TLV1570 is not directly connected to the input of
the converter. That makes it possible to insert a signal-conditioning circuit
between the multiplexer and the ADC. On the EVM, an amplifier [TLV2231
(U4)] can be inserted in the signal path (determined by JP3 and JP4). The
default gain of the amplifier is 1.0, but can be changed with R3 and R4 (as
shown in the following equation).

R3
R4
The SMA terminal can be used to connect the output of a function generator
directly to the input of the ADC. It is possible to set the input impedance to the
required value (R19). However, if the signal is routed via the multiplexer, R19
should be left open to avoid errors due to the current through this resistor.

2.4
Eight-Channel Direct Operation
In this mode, all eight channels of the ADC are accessible via J1. For this, both
JP1 and JP2 must be switched to the following positions:
JP1
JP2
UP
DOWN
2.5
Variable dc Voltage on Channel 7
To test the basic function of the ADC, the potentiometer R2 provides a dc
voltage between 0 V and the reference voltage. JP1 connects the wiper of the
potentiometer to channel 7.
JP1
DOWN
2.6
Loopback Mode on Channel 0
The onboard DAC (TLV5616) is used to run the board in a loopback mode. The
voltage, generated by the DAC, is connected to channel 0 with JP2.
JP2
UP
