4. The loop consisting of T1 primary (pins 1 and 3), Q2/Q3,
Q1, R1, the negative side of C108/C107 (see Fig.3), the
positive side of C105/C106 and back to T1 (pin1) on
Figure 4 should be a low inductance loop.
5. C8 should be physically close to T1, (pins 3 and 4). A half
inch is good. The same comment applies to C1 and T1,
(pins 1 and 10, 12, 14).
6. Beyond the above, the usual power supply layout consid-
eration should be followed, particularly with respect to
grounding.
The Xicor X9315
1. Insure that the potentiometer (pins 3, 5 and 6) never are
exposed to a voltage greater than Vcc or less than Vdd.
This applies during dynamic conditions such as applica-
tion of power.
2. Insure that the rate of rise of Vcc when power is applied is
between 0.2V/ms and 50V/ms as specified in the Xicor
X9315 data sheet.
3. To minimize the effect of temperature drift, use the poten-
tiometer where the performance of the circuit depends on
the ratiometric TC of the pot rather than the TC of the end
to end resistance. The ratiometric temperature coefficient
of the potentiometer is more than an order of magnitude
better than the temperature coefficient of Rtotal as speci-
fied in the data sheet.
