Description

Data Conversion IC Development Tools MAX1416 Evaluation Kit/Evaluation System

Manufacturer

Maxim Integrated

Series

MAX1415, MAX1416r

Datasheet

Interface Type

QSPI, Serial (SPI, Microwire)

Operating Supply Voltage

4.75 V to 5.25 V

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.
