Figure 8-10. DAC Block Diagram
8.9.1 Current DAC
The current DAC (IDAC) can be configured for the ranges 0 to
32 A, 0 to 256 A, and 0 to 2.048 mA. The IDAC can be
configured to source or sink current.
8.9.2 Voltage DAC
For the voltage DAC (VDAC), the current DAC output is routed
through resistors. The two ranges available for the VDAC are 0
to 1.024 V and 0 to 4.096 V. In voltage mode any load connected
to the output of a DAC should be purely capacitive (the output of
the VDAC is not buffered).
8.10 Up/Down Mixer
In continuous time mode, the SC/CT block components are used
to build an up or down mixer. Any mixing application contains an
input signal frequency and a local oscillator frequency. The
polarity of the clock, Fclk, switches the amplifier between
inverting or noninverting gain. The output is the product of the
input and the switching function from the local oscillator, with
frequency components at the local oscillator plus and minus the
signal frequency (Fclk + Fin and Fclk - Fin) and reduced-level
frequency components at odd integer multiples of the local
oscillator frequency. The local oscillator frequency is provided by
the selected clock source for the mixer.
Continuous time up and down mixing works for applications with
input signals and local oscillator frequencies up to 1 MHz.
