Table 5-1 Pin Functions
PIN TYPE DESCRIPTION
NAME Number
NC 1, 2, 6-12 No Connect No connect pin. Leave this pin floating or connected to GND.
T-SET 3 Input Connect resistor to adjust the heater temperature. Leave the pin floating to use factory programmed heater set point. Refer Section 7.3.1 for more details.
REF_Z 4,5 Output Reference voltage output. Connect an output capacitor between 10μF to 100μF for the best performance.
GND 13 GND This pin should be shorted to REF_GND pin.
REF_GND 14, 15 Ground Reference ground pin. This pin carries the current through the buried zener reference.
HEATM 16, 17 Power Heater power supply negative connection.
HEATP 18 Power Heater power supply positive connection.
VDD 19 Power Power supply for buried zener core and buffer.
OP_STBL 20 Output Active high output. Indicates the internal heater is stabilized at factory programmed temperature.
