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.
♦ Accepts Single-Ended or Differential Inputs
♦ Accepts Sine or Square Clock Input
♦ Proven PC Board Layout
♦ Convenient Test Points Provided On-Board
♦ Fully Assembled and Tested Surface-Mount

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 c omp le me nt d a ta outp uts . The MAX1201/
MAX1205 are 14-bit versions of the MAX1200.

Re c o m m e n d e d Eq u ip m e n t
You will ne e d the following e q uip me nt b e fore you
begin:
Data output signals are buffered by U1, U2, and U3
and provided at header J3 for evaluation.
Re fe re n c e In p u t
The MAX410 op amps designated as U8 and U9 on the
EV board buffer the REF+ and REF- inputs.
• A triple-output power supply (-3V, +5V, and +7V)
• A signal source, such as an HP8662A RF signal gen-
erator
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.
• Two stable precision voltage references
• A low-p ha s e -nois e c loc k s ourc e , s uc h a s a n
HP8662A pulse generator, filtered by a 10MHz low-
pass filter (Mini Circuits SLP-10.7).
The op amps have a maximum total supply-voltage rat-
• A logic analyzer, such as an HP16500B, to collect
ing of 10V. The supply rails have been set to V = -3V
SS
the data
and V = +7V to keep the signals well within the com-
CC
mon-mode range of these op amps.
The EV kit is s hip p e d fully a s s e mb le d a nd te s te d .
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.
Evluate:/MAX1205
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.
