CY8C24533
Analog System
The Analog system is composed of an 8-bit SAR ADC and four
configurable blocks. The programmable 8-bit SAR ADC is an
optimized ADC that runs up to 300 Ksps, with monotonic
guarantee. It also has the features to support a motor control
application.
Each analog block is comprised of an opamp circuit allowing the
creation of complex analog signal flows. Analog peripherals are
very flexible and can be customized to support specific appli-
cation requirements. Some of the more common PSoC analog
functions (most available as user modules) are:
■ Filters (2 and 4 pole band pass, low-pass, and notch)
■ Amplifiers (up to 2, with selectable gain to 48x)
■ Instrumentation amplifiers (1 with selectable gain to 93x)
■ Comparators (up to 2, with 16 selectable thresholds)
■ DACs (up to 2, with 6- to 9-bit resolution)
■ Multiplying DACs (up to 2, with 6- to 9-bit resolution)
■ High current output drivers (two with 30 mA drive as a Core
Resource)
■ 1.3V reference (as a System Resource)
■ DTMF dialer
■ Modulators
■ Correlators
■ Peak detectors
■ Many other topologies possible
Analog blocks are arranged in a column of three, which includes
one CT (Continuous Time) and two SC (Switched Capacitor)
blocks. The Analog Column 0 contains the SAR8 ADC block
rather than the standard SC blocks.
