| |
This patch adds the buffered mode device tree property for positive and negative inputs. Each option can be enabled independently.
In buffered mode, the input channel feeds into a high impedance input stage of the buffer amplifier. Therefore, the input can tolerate significant source impedances and is tailored for direct connection to external resistive type sensors such as strain gages or RTDs.
