Description
37
REF
AI/O
Reference Input/Output.
When PDREF/PDBUF = low, the internal reference and buffer are enabled, producing 5 V on this pin.
When PDREF/PDBUF = high, the internal reference and buffer are disabled, allowing an externally
supplied voltage reference up to AVDD volts. Decoupling with at least a 22 μF is required with or
without the internal reference and buffer. See the Reference Decoupling section.
38
REFGND
AI
Reference Input Analog Ground. Connected to analog ground plane.
39
IN
AI
Analog Input Ground Sense. Should be connected to the analog ground plane or to a remote sense ground.
40
VCC
P
High Voltage Positive Supply. Normally +7 V to +15 V.
41
VEE
P
High Voltage Negative Supply. Normally 0 V to 15 V (0 V in unipolar ranges).
43
IN+
AI
Analog Input. Referenced to IN.
45
TEMP
AO
Temperature Sensor Analog Output.
46
REFBUFIN
AI
Reference Buffer Input. When using an external reference with the internal reference buffer (PDBUF =
low, PDREF = high), applying 2.5 V on this pin produces 5 V on the REF pin. See the Voltage Reference
Input section.
47
PDREF
DI
Internal Reference Power-Down Input.
When low, the internal reference is enabled.
When high, the internal reference is powered down, and an external reference must be used.
48
PDBUF
DI
Internal Reference Buffer Power-Down Input.
When low, the buffer is enabled (must be low when using internal reference).
When high, the buffer is powered-down.
49
EPAD3
NC
Exposed Pad. The exposed pad is not connected internally. It is recommended that the pad be
soldered to VEE.
1 AI = analog input; AI/O = bidirectional analog; AO = analog output; DI = digital input; DI/O = bidirectional digital; DO = digital output; P = power.
2 In serial configuration mode (SER/PAR = high, HW/SW = low), this input is programmed with the serial configuration register and this pin is a don’t care. See the
3 LFCSP_VQ package only.
