Problem: Internal oscillator does not work.
The internal-oscillator mode is a feature of the
MAX1416/MAX1415 only, and is not supported on the
MX7705. The MX7705 requires an external clock, and
can only be used with INT = 0. To observe the internal
oscillator driving the MCLKOUT pin, U1 must be a
MAX1416 or MAX1415, and the clock register must
have INT = 1 and CLKDIS = 0.
Problem: Measurements are erratic or unstable or
there is poor accuracy.
Check the reference voltage using a digital voltmeter.
Use an oscilloscope to check for noise. When probing
for noise, keep the oscilloscope ground-return lead as
short as possible, preferably less than 1/2 in (10mm).

Problem: Unacceptable errors when measuring a
transducer.
Although most signal sources can be connected direct-
ly to the MAX1416’s analog input, some high-imped-
ance signal sources may require using the internal
input buffer (BUF = 1).
Problem: PDA hot-sync software or other device
software interferes with EV kit software.
COM ports can only be used by one device at a time.
Disable PDA hot-sync manager.
