verter input. A0 is the least significant address bit (i.e.,
channel 1 is selected when A0 = 1 and A1 = 0). The
multiplexer is designed to be operated in a differential mode.
For single-ended inputs, the CHx
–
input for the channel
under selection must be connected to the ground reference
associated with the input signal.

DC/DC Converter
An on-board, TC7660H-type charge pump supplies
negative bias to the converter circuitry, as well as to external
devices. The charge pump develops a negative output
voltage by moving charge from the power supply to the
reservoir capacitor at V
SS
by way of the commutating
capacitor connected to the CAP
+
and CAP
–
inputs.
The charge pump clock operates at a typical frequency
of 100kHz. If lower quiescent current is desired, the charge
pump clock can be slowed by connecting an external ca-
pacitor from the OSC pin to V
DD
. Reference typical charac-
teristics curves.
APPLICATIONS
Design Example
Figure 6 shows a typical TC534 interrupt-driven applica-
tion. Timing and component values are calculated from
equations and recommendations made in the Dual Slope
Integrating Converter and Programming the TC530/534
sections of this document. The EOC connection to the
processor INT input is for interrupt-driven applications only.
(In polled systems, the EOC output is available on D
OUT
).
