Figure 6. A 2:1 Multiplexing Two LTC6915’s
with Daisy Chained Gain Control
Multiplexing Two LTC6915’s
Send a gain code of 0000 to one IC to set its output to a
high impedance state and send a gain code other than 0000
to the second IC to set it for normal amplification. If both
devices are ON, the 200Ω resistors protect the outputs.
The sense pin connection maintains gain accuracy for
loads 1k or greater.
