8051 CODE
Sharing the Serial Interface
The LTC1292/LTC1297 can share the same two-wire
serial interface with other peripheral components or other
LTC1292/LTC1297s (Figure 6). In this case, the CS signals
decide which LTC1292 is being addressed by the MPU.
ANALOG CONSIDERATIONS
Grounding
The LTC1292/LTC1297 should be used with an analog
ground plane and single point grounding techniques. Do
not use wire wrapping techniques to breadboard and
evaluate the device. To achieve the optimum performance
