Quick Start
Recommended Equipment
MAX1169EVC16 (MAX1169EVKIT, 68HC16MODULEDIP, HSI2CMOD) power supplies: +20V 0.5A 0.2A Analog signal source: +4.096V Windows 95/98/2000/XP computer with available serial (COM) port 9-pin extension cable (straight through female male)
Ensure that ON/OFF switch (SW1) 68HC16 module position. Connect +20V power supply terminal block 68HC16 module (J2), which located next SW1, module. Observe polarity marked board. Carefully connect I2C-compatible module MAX1169 board aligning 20-pin connector. Gently press them together. boards should flush against another. Connect power supply between AVDD AGND pads MAX1169 board. Connect 9-pin serial cable from computer's serial port connector 68HC16 module (J3). Install MAX1169 software your computer running INSTALL.EXE program ROM. program files copied icons created programs section Windows Start menu. Turn 68HC16 module sliding position, turn power supplies. Start MAX1169 program clicking icon programs section Windows Start menu.
Procedure
turn power until connections made: Verify that jumpers JU0-JU3 connected pins 1-2. This sets I2C-compatible slave address MAX1169 0x7F. Verify that jumper OFF. This enables internal 4.096V (typ) reference. Verify that jumper OFF. This disconnects analog input buffer (U2) from AIN. Carefully connect 68HC16-module board I2C-compatible module board aligning 40-pin connector. Gently press them together. boards should flush against another.
MAX1169 Evaluation System/Evaluation
Windows program prompts click automatic serial port selection. When click KIT1169.C16 file automatically downloads module. Wait approximately download complete. software uses value typed VREF field translate digital code voltage. default +4.096V reference value. First, measure reference voltage MAX1169. Then, after typing measured reference value into VREF field, press VREF button. Apply analog input signal VREF) between AGND. Observe voltage code labels Windows program.
Detailed Description Hardware
MAX1169 System
MAX1169 system complete 16-bit dataacquisition system consisting MAX1169 kit, 68HC16 module, I2C-compatible module. complete MAX1169 system used evaluate MAX1169 16-bit, I2C-compatible, analog-to-digital converter (ADC). Quick Start section setup operating instructions. 68HC16 Module 68HC16 module utilizes Motorola's MC68HC16Z1 fully assembled tested. This module provides working example design customers have chosen their system have ability connect MAX1169 their system. Windows software downloads assembled program onboard random access memory 68HC16 module. more information, refer 68HC16 module data sheet. I2C-Compatible Module I2C-compatible module provides 2-wire interface peripheral 68HC16 module using Altera EPM3256AQC208-10 PLD. This peripheral implemented utilizing DI2CM core from Digital Core Design. I2C-compatible module allows 68HC16 module compatible with mode (1.7MHz), fast mode (400kHz), standard mode (100kHz).

Detailed Description Software
main window evaluation software shown Figure This window displays voltage code analog input signal AIN. software supports both manual read automatic read operations. I2Ccompatible serial-clock (SCL) frequency selectable: mode (1.7MHz), fast mode (400kHz), standard mode (100kHz). HS-mode I2C-compatible systems, communication arbitration always done either fast mode standard mode. Only data transmitted received HS-mode speeds. software expects 4.096V reference execution; however, this value changed software accommodate different reference value. Table describes controls main window evaluation software.
External Reference
disable MAX1169's internal +4.096V (typ) reference, select external reference mode with shunt JU4. Apply external reference voltage between pads MAX1169 board. After measuring external reference voltage, enter into VREF field software (without volt unit) press VREF button.
MAX1169
MAX1169 board provides proven layout evaluating MAX1169 16-bit, I2C-compatible obtained separately without 68HC16 module I2C-compatible module. MAX1169 contains 16-bit accurate analog input buffer (U2), connected unity-gain configuration. been provided MAX1169 board evaluating MAX1169 with external reference. Refer MAX1169 data sheet ensure interface timing specifications when user-supplied I2Ccompatible interface used.
