I2C Address and data for Gain control
If the user wants to send I2C with another method, check the below I2C address and data.
The MAX49918 uses an input pin (A0) that determines the least-significative bit (LSB) of the I2C device address word
below.
Bit 6 Bit 5

The register address to set the gain is 0x00. And the data to set the gain is shown in the table below.

Output Voltage

The MAX49918 has two reference inputs (REF1 and REF2) to set the device in either unidirectional or bidirectional
operation mode. Connect the REF1 and REF2 inputs to low-impedance voltage source(s) to set the MAX49918 output
(V ) reference level. Do not connect REF1 and REF2 inputs to any voltages lower than GND or higher than V
OUT
is defined as the average voltage of V
Use the following equations to set the gain:
V = V * GAIN + V
OUT SENSE REF
Where V = V - V
SENSE RS+ RS-
The default state of the EV kit is REF1 = VDD and REF2 = GND, i.e., it is in bidirectional mode with V
Refer to the MAX49918 data sheet application information for more detail about the reference.
