Analog System

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 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. The number of blocks is dependant on the device family which is detailed in the table PSoC Device Characteristics on page 4.
