General Description

The MAX1416 evaluation kit (EV kit) is an assembled and

tested printed-circuit board (PCB) that demonstrates the

MAX1416 multichannel, 16-bit, sigma-delta data-acquisi-

tion system. Windows

98/2000/XP-compatible software

provides a convenient user interface to exercise the fea-

tures of the MAX1416.

Order the complete evaluation system (EV system)

(MAX1416EVC16) for a comprehensive evaluation of the

MAX1416 using a personal computer. Order the EV kit

(MAX1416EVKIT) if the 68HC16MODULE-DIP has been

purchased with a previous Maxim EV system, or for cus-

tom use in other microcontroller (µC)-based systems.

To evaluate the MAX1415, request a free sample of the

MAX1415EUE. To evaluate the MX7705, request a free

sample of the MX7705EUE.

*This limited temperature range applies to the EV kit PCB only.

The MAX1416 IC temperature range is -45°C to +85°C.

Note: The MAX1416 software is designed for use with the

complete EV system (MAX1416EVC16). It includes a

68HC16MODULE-DIP module, USBTO232, and a

MAX1416EVKIT. If the MAX1416 evaluation software is not

used, the MAX1416EVKIT board can be purchased by itself,

without the µC.

MAX1416 Evaluation Kit/Evaluation System 5) Connect the +5VDC power source to the MAX1416 EV kit at terminal block TB1. Observe the polarity marked on the board. 6) Connect the +7VDC to +20VDC power source to the µC module at the terminal block located next to the on/off switch, along the top-edge of the µC module. Observe the polarity marked on the board. 7) Connect a cable from the computer’s serial port to the µC module. If using a 9-pin serial port, use a straight-through, 9-pin female-to-male cable.

Evaluate: MAX1416/MAX1415/MX7705 MAX1416 Evaluation Kit/Evaluation System Reference Voltage The evaluation software assumes a 2.500V reference voltage, unless otherwise specified. To override this value, go to the Measurement tab and type the new reference voltage next to REF voltage. Software Listing Table 1. Jumper Functions JUMPER JU1 The EV kit software disk contains the driver source and header file. Refer to DRV1416.cpp and DRV1416.h.
PAGE 5
MAX1416 Evaluation Kit/Evaluation System 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.
