10.8.1 Introduction
The Analog Continuous Time PSoC blocks are built
around an operational amplifier. There are several ana-
log muxes that are controlled by register-bit settings in
the control registers that determine the signal topology
inside the block. There is also a precision resistor matrix
that is located in the feedback path for the op-amp, and
is controlled by register-bit setting. There is also an ana-
log comparator connected to the output OUT, which con-
verts analog comparisons into digital signals.
There are five discrete outputs from this block. These
outputs are:
1.
2.
3.
This block supports Programmable Gain or attenuation
Op-Amp Circuits, (Differential Gain) Instrumentation
Amplifiers (using two CT Blocks), Continuous time high
frequency anti-aliasing filters, and modest response-time
analog comparators.

The analog output bus (ABUS), which is an analog
bus resource that is shared by all of the analog
blocks in the analog column for that block.
The comparator bus (CBUS), which is a digital bus
that is a resource that is shared by all of the analog
blocks in a column for that block.
The output bus (OUT, GOUT and LOUT), which is
an analog bus resource that is shared by all of the
analog blocks in a column and connects to one of
the analog output buffers, to send a signal externally
to the device.
