The Analog System is composed of six configurable blocks, each
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 application requirements.
Some of the more common PSoC analog functions (most
available as user modules) are:

■

Analog-to-digital converters (up to two, with 6 to 14-bit 
resolution, selectable as Incremental, Delta Sigma, and SAR)

■

Filters (two and four pole band-pass, low-pass, and notch)

■

Amplifiers (up to two, with selectable gain to 48x)

■

Instrumentation amplifiers (one with selectable gain to 93x)

■

Comparators (up to two, with 16 selectable thresholds) 

■

DACs (up to two, with 6 to 9-bit resolution)

■

Multiplying DACs (up to two, with 6 to 9-bit resolution)

■

High current output drivers (two with 30 mA drive as a PSoC 
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, as shown in
