PIC24FV16KM204 FAMILY
21.0 DUAL OPERATIONAL
AMPLIFIER MODULE
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, refer to the
“PIC24F Family Reference Manual”,
Section 61. “Operational Amplifier
(Op Amp)” (DS30505). Device-specific
information in this data sheet supersedes
the information in the “PIC24F Family
Reference Manual”.
PIC24FV16KM204 family devices include two opera-
tional amplifiers to complement the microcontroller’s
other analog features. They may be used to provide
analog signal conditioning, either as stand-alone
devices or in addition to other analog peripherals.
The two op amps are functionally identical; the block
diagram for a single amplifier is shown in Figure 21-1.
Each op amp has these features:
• Internal unity-gain buffer option
• Multiple input options each on the inverting and
non-inverting amplifier inputs
• Rail-to-rail input and output capabilities
