Analog System

The analog system consists of six configurable blocks, each

consisting of an opamp circuit that allows 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:

■ ADCs (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)

■ 1.3 V 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 continuous time (CT) and two switched capacitor (SC)

blocks, as shown in Figure 3
