MAX1200/MAX1201/MAX1205 Evaluation Kits
General Description
The MAX1200/MAX1201/MAX1205 evaluation kits (EV
kits) are assembled and tested PC boards that include
the basic components necessary to drive either the 16-bit
MAX1200 or 14-bit MAX1201/MAX1205 analog-to-digital
converters (ADCs). Connectors for power supplies, ana-
log inputs, and digital outputs simplify connections to the
device. The PC board layouts are optimized for best
dynamic performance. Each EV kit is fully assembled and
tested, and includes a MAX1200, MAX1201, or MAX1205
(as requested) that is soldered and ready to test.

6) Turn on the EV kit’s power supplies.
7) Press momentary switch SW1 to trigger self-calibra-
tion.
8) Turn on the input signal source.
9) Collect data using the logic analyzer.
Hardware Description
The MAX120x EV kit accepts a differential input signal
between IN+AP and IN-AP, or it can accept a single-
ended (i.e., ground-referenced) input signal at IN. The
PC board can also accommodate a Balun transformer
at T1; however, transformer-coupling the input may
degrade signal performance.
U12, the MAX1200, is a 16-bit, 1Msps ADC with parallel
two’s complement data outputs. The MAX1201/
MAX1205 are 14-bit versions of the MAX1200.
Data output signals are buffered by U1, U2, and U3
and provided at header J3 for evaluation.
_________________________Quick Start
Recommended Equipment
You will need the following equipment before you
begin:
•
A triple-output power supply (-3V, +5V, and +7V)
•
A signal source, such as an HP8662A RF signal gen-
erator
•
Two stable precision voltage references
•
A low-phase-noise clock source, such as an
HP8662A pulse generator, filtered by a 10MHz low-
pass filter (Mini Circuits SLP-10.7).
•
A logic analyzer, such as an HP16500B, to collect
the data
The EV kit is shipped fully assembled and tested.
Follow these steps to verify board operation.
Do not
turn on the power supply until all connections are
completed.
1) Connect the power supplies to the -3V, +7V, +5V,
AGND, and DGND pads. For best results, use sepa-
rate analog and digital leads, connecting AGND to
DGND close to the power supply’s common termi-
nal.
2) Connect a signal source to the IN or IN+AP/IN-AP
inputs. If using differential inputs, common-mode
voltage should be halfway between REF+ and REF-.
3) Connect the voltage references to the REF+ and
REF- inputs.
4) Connect a sine-wave clock source to the CLK_SINE
input. If using a square wave instead of a sine wave,
connect it to the CLK_SQ input instead.
5) Turn on the logic analyzer and connect it to header
J3. Configure it to receive data on the rising edge of
the DAV strobe signal.
Reference Input
The MAX410 op amps designated as U8 and U9 on the
EV board buffer the REF+ and REF- inputs.
The MAX410 op amp designated as U7 on the EV board
buffers resistor-dividers R2/R1/R3, providing a common-
mode voltage level halfway between REF+ and REF-.
Trim pot R1 adjusts the common-mode voltage.
The op amps have a maximum total supply-voltage rat-
ing of 10V. The supply rails have been set to V
SS
= -3V
and V
CC
= +7V to keep the signals well within the com-
mon-mode range of these op amps.
