The 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 EZ-Color 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, or 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 40 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.
