Analog System
The Analog System is composed of three 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 require-
ments. Some of the more common PSoC analog functions (most
available as user modules) are:
■ Analog-to-digital converters (one with 6 to 14-bit resolution,
selectable as Incremental, Delta Sigma, and SAR)
■ Filters (two pole band-pass, low-pass, and notch)
■ Amplifiers (one with selectable gain to 48x)
■ Comparators (one with 16 selectable thresholds)
■ DACs (one with 6 to 9-bit resolution)
■ Multiplying DACs (one with 6 to 9-bit resolution)
■ High current output drivers (one with 30 mA drive as a Core
Resource)
■ 1.3V reference (as a System Resource)
■ 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.
