Specifications of MAX1270EVKIT+

• Rohs: yes
• Product: Evaluation Kits
• Tool Is For Evaluation Of: MAX1270
• Interface Type: Serial
• Operating Supply Voltage: 8 V to 12 V
• Maximum Operating Temperature: + 70 C
• Minimum Operating Temperature: 0 C

The MAX1270 EV system operates from a user-sup-
plied +8V to +12V DC power supply. Windows 3.1/95
software running on an IBM PC interfaces to the EV sys-
tem board through the computer’s serial-communica-
tions port. The software can be operated with or without
a mouse. Refer to the Quick Start section for setup and
operating instructions.
The MAX1270 EV kit provides a proven PC board layout
to facilitate evaluation of the MAX1270. Apply your sys-
tem’s ±12V power-supply rails to the OPAMP+ and
OPAMP- terminals. Connect GND to your system
ground return. The OPAMP+ input powers a MAX1615
linear regulator and a MAX6141 voltage reference. It
must be interfaced to appropriate timing signals for
proper operation.
Connect your three-wire interface to SCLK, DIN, DOUT,
and GND. Leave R3 and R4 open. If you do not drive
CS, install a 100Ω resistor at R5. If you do not drive
SHDN, install a 100Ω resistor at R2. Make sure JU1 is in
position 2-3 (factory setting). Refer to the MAX1270
data sheet for waveforms and timing requirements.

MAX1270/MAX1271
Stand-Alone EV Kit
The MAX1270 EV board may be used to evaluate the
MAX127 or MAX128 with a user-supplied, 2-wire con-
troller and software. Replace U1 with the MAX127ACNG
or MAX128ACNG. Cut the default trace on the back of
the board under JU1 (marked with an arrow). Short pins 1
and 2 of jumper JU1. Connect your two-wire interface to
SCL, SDA, and GND. Install 100Ω resistors at R2, R3, R4,
and R5. With the address select pins pulled down by R3,
R4, and R5, the two-wire device address is 01010000 for
writing commands to the part and 01010001 for reading
data from the part. Refer to the MAX127 data sheet for
waveforms and timing requirements.
Note: The MAX1270 EV system software does not
support the MAX127 or MAX128.
Recommended Equipment
You will need the following equipment before you
begin:
• A small DC power supply, +8V to +12V at 200mA
