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.
