Specifications of MAX1169EVKIT

• Interface Type: I2C, Serial

The main window of the evaluation software is shown in
Figure 1. This window displays the voltage and code of
the analog input signal AIN. The software supports both
manual read or automatic read operations. The I
compatible serial-clock (SCL) frequency is selectable:
HS mode (1.7MHz), fast mode (400kHz), or standard
mode (100kHz). In HS-mode I
the communication and arbitration are always done in
either fast mode or standard mode. Only data can be
transmitted or received at HS-mode speeds. The soft-
ware expects the use of a 4.096V reference on execu-
tion; however, this value can be changed in the soft-
ware to accommodate a different reference value.
Table 1 describes the controls in the main window of
the evaluation software.
To disable the MAX1169’s internal +4.096V (typ) refer-
ence, select external reference mode with a shunt on
JU4. Apply the new external reference voltage between
the REF and GND pads on the MAX1169 EV kit board.
After measuring the external reference voltage, enter it
into the V
and press the Set V
The MAX1169 EV system is a complete 16-bit data-
acquisition system consisting of a MAX1169 EV kit, a
68HC16 µC module, USBTO232, and an HS I
patible module.
The complete MAX1169 EV system is used to evaluate
the MAX1169 16-bit, I
converter (ADC). See the Quick Start section for setup
and operating instructions.

The 68HC16 µC module utilizes Motorola’s
MC68HC16Z1 µC and is fully assembled and tested.
This module provides a working example of a µC
design for customers who have not yet chosen one for
their system or who do not have the ability to connect
the MAX1169 EV kit to their own system. The Windows
software downloads an assembled program to the on-
board random-access memory of the 68HC16 module.
For more information, refer to the 68HC16 module data
sheet.
The HS I
face peripheral for the 68HC16 µC module using an
Altera EPM3256AQC208-10 PLD. This peripheral is
implemented in the PLD by utilizing the DI2CM core
from Digital Core Design. The HS I
ule allows the 68HC16 module to be compatible with
HS mode (1.7MHz), fast mode (400kHz), and standard
mode (100kHz). This module is not required when eval-
uating the MAX1169 EV kit with a user-supplied I
compatible interface. For more information, refer to the

The MAX1169 EV kit board provides a proven layout for
evaluating the MAX1169 16-bit, I
and can be obtained separately without the 68HC16
module, USBTO232, and HS I
The MAX1169 EV kit contains a 16-bit accurate analog
input buffer (U2), connected in the unity-gain configura-
tion. A REF pad has been provided on the MAX1169 EV
kit board for evaluating the MAX1169 with an external
reference. Refer to the MAX1169 data sheet to ensure
all interface timing specifications are met when a user-
