3.11 AD Converter
TMP93CS44/S45 incorporate a high-speed, high-precision 10-bit analog/digital converter (AD
converter) with 8-channel analog input.
Figure 3.11.1 is a block diagram of the AD converter. The 8-channel analog input pins (AN0 to
AN7) are also used as input-only port 5 and can be also used as input ports.
Figure 3.11.1 Block Diagram of AD Converter
Note 1:
When the power supply current is reduced in IDLE2, IDLE1, STOP mode, there is possible to set
a standby enabling the internal comparator due to a timing. Stop operation of AD converter before
execution of “HALT” instruction.
Note 2:
In regard to the lowest operation frequency.
The operation of AD converter is guaranteed with clock of fFPH ≥ 4 MHz (Used fc clock). Is not
guaranteed with fs clock.
