specified. Unipolar configuration - Pins 1 and 2 to Pin 9, Pin 4

to Pin 4. Bipolar configuration - Pin 1 to Pin 9, 50

Ω resistor Pin 4 to Pin 6.

2/

Adjustable to 0

3/

In subgroup 1, the reference output is loaded with 0.5mA nominal reference current, 1.0mA bipolar offset current and 0.1mA additional current. In

subgroups 2 and 3, only the 0.5mA reference input current is applied. The reference must be buffered to supply external loads at elevated

temperatures.

4/

All bits low, A0, A1, A2, A3, LOGIC "0"; A0, A1, A2, A3 initialized to Logic "1", each 4-bit register set to LOGIC "1", and A0, A1, A2 set sequentially

to LOGIC "0" and back to LOGIC "1" to latch data into first rank.

5/

A3 set to LOGIC "0" and back to LOGIC "1" to latch full-scale output into second rank.
