13 - A/D CONVERTER
13.1 - A/D Converter Module
A 10-bit A/D converter with 2 x 16 multiplexed
input channels and a sample and hold circuit is
integrated on-chip. This A/D Converter does not
have the self-calibration feature. Thus, guaran-
teed Total Unadjusted Error is + 2 LSB. Refer to
Section 20.3.1 - A/D Converter Characteristics for
detailled characteristics. The sample time (for
loading the capacitors) and the conversion time is
programmable and can be adjusted to the exter-
nal circuitry. Convertion time is fully equivalent to
the one of previous generation A/D self-calibrated
Converter.
To remove high frequency components from the
analog input signal, a low-pass filter must be con-
nected at the ADC input.
Overrun error detection/protection is controlled by
the ADDAT register. Either an interrupt request is
generated when the result of a previous conver-
sion has not been read from the result register at
the time the next conversion is complete, or the
next conversion is suspended until the previous
result has been read. For applications which
require less than 16 analog input channels, the
remaining channel inputs can be used as digital
input port pins.
The A/D converter of the ST10F280 supports four
different conversion modes:
Single channel conversion mode the analog
level on a specified channel is sampled once and
converted to a digital result.
Single channel continuous mode the analog
level on a specified channel is repeatedly sampled
and converted without software intervention.
Auto scan mode the analog levels on a pre-spec-
ified number of channels are sequentially sampled
and converted.
Auto scan continuous mode the number of
pre-specified channels is repeatedly sampled and
converted.
Channel Injection Mode injects a channel into a
running
sequence. The peripheral event controller stores
the conversion results in memory without entering
and exiting interrupt routines for each data transfer.
