8-bit A/D and D/A converter
PCF8591
7.5
Reference voltage
For the D/A and A/D conversion either a stable external
voltage reference or the supply voltage has to be applied
to the resistor divider chain (pins VREF and AGND).
The AGND pin has to be connected to the system analog
ground and may have a DC off-set with reference to VSS.
A low frequency may be applied to the VREF and AGND
pins. This allows the use of the D/A converter as a
one-quadrant multiplier; see Chapter 15 and Fig.7.
The A/D converter may also be used as a one or two
quadrant analog divider. The analog input voltage is
divided by the reference voltage. The result is converted to
a binary code. In this application the user has to keep the
reference voltage stable during the conversion cycle.
7.6
Oscillator
An on-chip oscillator generates the clock signal required
for the A/D conversion cycle and for refreshing the
auto-zeroed buffer amplifier. When using this oscillator the
EXT pin has to be connected to VSS. At the OSC pin the
oscillator frequency is available.
If the EXT pin is connected to VDD the oscillator output
OSC is switched to a high-impedance state allowing the
user to feed an external clock signal to OSC.
