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 V
The AGND pin has to be connected to the system analog
ground and may have a DC off-set with reference to V
A low frequency may be applied to the V
pins. This allows the use of the D/A converter as a
one-quadrant multiplier; see Chapter 15 and Fig.6.
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.

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 V
oscillator frequency is available.
If the EXT pin is connected to V
OSC is switched to a high-impedance state allowing the
user to feed an external clock signal to OSC.
