Integrator Output Zero Phase
The comparator delay and the controller’s response
latency may result in overshoot, causing charge
buildup on the integrator at the end of a conversion.
This charge must be removed or performance will
degrade. The integrator output zero phase should be
activated (AB = 00) until CMPTR goes high. It is
absolutely critical that this phase be terminated
immediately so that overshoot is not allowed to occur in
the opposite direction. At this point, it can be assured
that the integrator is near zero. Auto-zero should be
entered (AB = 01) and the TC5XX held in this state until
the next cycle is begun (see Figure 8-2).

Using the TC510/TC514
8.7.1
NEGATIVE SUPPLY VOLTAGE
CONVERTER (TC510, TC514)
A capacitive charge pump is employed to invert the
voltage on VDD for negative bias within the TC510/
TC514. This voltage is also available on the VOUT– pin
to provide negative bias elsewhere in the system. Two
external capacitors are required to perform the
conversion.
Timing is generated by an internal state machine driven
from an on-board oscillator. During the first phase,
capacitor CF is switched across the power supply and
charged to VS+. This charge is transferred to capacitor
COUT– during the second phase. The oscillator
normally runs at 100 kHz to ensure minimum output
ripple. This frequency can be reduced by placing a
capacitor from OSC to VDD. The relationship between
the capacitor value is shown in Section 2.0 “Typical
.
8.7.2
ANALOG INPUT MULTIPLEXER
(TC514)
The TC514 is equipped with a four-input differential
analog multiplexer. Input channels are selected using
select inputs (A1, A0). These are high-true control
signals (i.e., channel 0 is selected when (A1, A0 = 00).
