CY8C24123A CY8C24223A, CY8C24423A

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:

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 Figure 2.
