Description
Analog Input. Referenced to IN−.
Temperature Sensor Analog Output.
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.
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.
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.
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
Hardware Configuration section and Software Configuration section.
