Description
The TPAFE0808 has eight input/output pins, which
can be configured to be ADC input, or DAC output, or
General purpose I/O pins.
A 12bit ADC is integrated in TPAFE0808, which can
be connected to each input/output pin by an eight-
channel multiplexer. The ADC input range is 0~VREF
or 0~2*VREF.
TPAFE0808 has eight channel 12bit DAC, which can
be connected to corresponding input/output pin. The
DAC output range is 0~VREF or 0~2*VREF.
TPAFE0808 has an internal 2.5V reference, and it
can also use external reference when internal
reference is turned off.
It also has an internal temperature sensor which can
measure die temperature.
The TPAFE0808 is available in 16-lead MIS 3x3, as
well as a 16-ball WLCSP, and operates over a
temperature range of −40°C to +125°C.
