Some devices in this PSoC family have an analog multiplex bus that can connect to every GPIO pin. This bus can also connect to the analog system for analysis with comparators and analog-to-digital converters. It can be split into two sections for simultaneous dual-channel processing. Some of the more common PSoC analog functions (most available as user modules) are: ■ Analog-to-digital converters (6 to 14-bit resolution, up to 4, selectable as Incremental or Delta Sigma) ■ Dedicated 10-bit SAR ADC with sample rates up to 142 ksps ■ Synchronized, simultaneous Delta Sigma ADCs (up to 4) ■ Filters (2 to 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 6, 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 (up to 4 with 30 mA drive) ■ 1.3 V reference (as a System Resource) ■ DTMF Dialer ■ Modulators ■ Correlators ■ Peak detectors ■ Many other topologies possible Figure 2.
