Analog System

The Analog System is composed of 12 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 listed below.

■ Analog-to-digital converters (up to 4, with 6- to 14-bit resolution,

selectable as Incremental, Delta Sigma, and SAR)

■ Filters (2, 4, 6, and 8 pole band-pass, low-pass, and notch)

■ Amplifiers (up to 4, with selectable gain to 48x)

■ Instrumentation amplifiers (up to 2, with selectable gain to 93x)

■ Comparators (up to 4, with 16 selectable thresholds)

■ DACs (up to 4, with 6- to 9-bit resolution)

■ Multiplying DACs (up to 4, with 6- to 9-bit resolution)

■ High current output drivers (four 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 provided in columns of three, which includes

one CT (Continuous Time) and two SC (Switched Capacitor)

blocks, as shown in the figure below.
