PIC24FV16KM204 FAMILY
19.0 12-BIT A/D CONVERTER WITH
THRESHOLD DETECT
Note:
This data sheet summarizes the features of
this group of PIC24F devices. It is not
intended to be a comprehensive reference
source. For more information on the 12-Bit
A/D Converter with Threshold Detect, refer
to the âPIC24F Family Reference Manualâ,
Section 51. â12-Bit A/D Converter with
Threshold Detectâ (DS39739).
The PIC24F 12-bit A/D Converter has the following key
features:
⢠Successive Approximation Register (SAR)
Conversion
⢠Conversion Speeds of up to 100 ksps
⢠Up to 32 Analog Input Channels (Internal and
External)
⢠Multiple Internal Reference Input Channels
⢠External Voltage Reference Input Pins
⢠Unipolar Differential Sample-and-Hold (S/H)
Amplifier
⢠Automated Threshold Scan and Compare
Operation to Pre-Evaluate Conversion Results
⢠Selectable Conversion Trigger Source
⢠Fixed-Length (one word per channel),
Configurable Conversion Result Buffer
⢠Four Options for Results Alignment
⢠Configurable Interrupt Generation
⢠Operation During CPU Sleep and Idle modes
The 12-bit A/D Converter module is an enhanced
version of the 10-bit module offered in some PIC24
devices. Both modules are Successive Approximation
Register (SAR) converters at their cores, surrounded
by a range of hardware features for flexible
configuration. This version of the module extends
functionality by providing 12-bit resolution, a wider
range of automatic sampling options and tighter
integration with other analog modules, such as the
CTMU, and a configurable results buffer. There is a
legacy 10-bit mode on this A/D to allow the option to run
with lower resolution in order to obtain higher
throughput. This module also includes a unique
Threshold Detect feature that allows the module itself
to make simple decisions based on the conversion
results.
A simplified block diagram for the module is illustrated
in Figure 19-1.
