Application Notes

a- Input Interface:

Recommended input turn-on current for all six drive signals is 5-8mA.

For higher noise immunity the tri-state differential buffer, DS34C87, is recommended as

shown in Fig. 4.

Note : Connect LinA to non-inverting output for a non-inverting input logic.

Connect LinA to inverting output for an inverting input logic.

b-Temperature Sensor Output:

For both negative and positive temperature measurement capability, Contact the Factory.
