Pin Functions

PIN TYPE EQUIVALENT CIRCUIT DESCRIPTION
NAME NO.
GND A1 Ground Ground reference for the device
VDD A2 Power Supply voltage
TAO B1 Analog Output LMT70 LMT70A 30080539.gif Temperature analog output pin
T_ON B2 Digital Input LMT70 LMT70A 30080538.gif T_ON pin. Active High input.
If T_ON = 0, then the TAO output is open.
If T_ON = 1, then TAO pin is connected to the temperature output voltage.
Tie this pin to VDD if not used.
