Page 3: Introduction
The phase shift and cutoff frequency of this EVM can be modified by changing external capacitors. The INA1620EVM allows external resistors to be used instead of the internal thin-film resistors INA1620. This may be useful for applications where the excellent matching of the INA162 resistors is desired for another use. -
Page 4: The Ina1620Evm
RightChannelOutp The INA1620EVM also allows the use of external resistors to set the amplifier gain. Note that external resistors must be used if the thin-film resistors in the INA1620 are to be used for other purposes. Equation 4... -
