The Analog system consists 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 consists 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:

■

Filters (2 band pass, low-pass)

■

Amplifiers (up to 2, with selectable gain to 48x)

■

Instrumentation amplifiers (1 with selectable gain to 93x)

■

Comparators (1, with 16 selectable thresholds) 

■

DAC (6 or 9 -bit DAC)

■

Multiplying DAC (6 or 9 -bit DAC)

■

High current output drivers (two with 30 mA drive)

■

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.
