General Description
The MAX1198 evaluation kit (EV kit) is a fully assembled
and tested circuit board that contains all the components
necessary to evaluate the performance of the
MAX1195–MAX1198 dual 8-bit analog-to-digital converters (ADCs). The MAX1195–MAX1198 accept differential
or single-ended analog inputs and the EV kit allows for
evaluation of each ADC with both types of inputs from
one single-ended analog signal. The digital output produced by the ADC can be easily sampled with a userprovided high-speed logic analyzer or data-acquisition
system. The EV kit operates from 3.3V and 2.5V
(MAX1198) power supplies. It includes circuitry that generates a clock signal from an AC signal provided by the
user. The EV kit comes with the MAX1198 installed. Order
free samples of the pin-compatible MAX1195, MAX1196,
or MAX1197 to evaluate these parts.

2) Connect the clock function generator to the CLOCK
SMA connector.
b) To evaluate differential analog signals on channel B, verify that shunts are installed on pins
2 and 3 of jumpers JU3 and JU4. Connect the
output of the analog bandpass filter to the
D/E_INB SMA connector. For single-ended analog signal evaluation on channel B, verify that
shunts are installed on pins 1 and 2 of jumpers
JU3 and JU4, and connect the output of the
bandpass filter to the S/E_INB SMA connector.
Note: Both channels can be operated independently
or simultaneously.
5) Connect the logic analyzer to the header (J1). For
nonmultiplexed output operation, channel A (channel B) data is captured on J1-1 (J1-27) through J115 (J1-41). If evaluating the multiplexed outputs of
the MAX1196, channel A and channel B data is
captured on a single 8-bit bus (J1-1 through J1-15)
and the A/B indicator signal can be monitored on
J1-23 (see Table 4 for bit locations and J1 header
designations). The system clock for both multiplexed and nonmultiplexed output operation is
available on pin J1-43.

specified below), the ADC can be evaluated with both
types of inputs by supplying only one
single-ended analog signal to the EV kit.
8) Turn on both power supplies.
The EV kit was designed as a four-layer PC board to
optimize the performance of the MAX1198. Separate
analog and digital power planes minimize noise coupling between analog and digital signals. For simple
operation, the EV kit is specified to have 3.3V and 2.5V
power supplies applied to analog and digital power
planes, respectively. However, the digital plane can be
operated down to 1.7V without compromising performance. The logic analyzer’s threshold must be adjusted accordingly.
Access to the outputs, channel A and channel B, is
provided through connector J1. The 50-pin connector
easily interfaces directly with a user-provided logic
analyzer or data-acquisition system.
9) With a voltmeter, verify that 1.32V is measured
across test points TP1 and TP2. If the voltage is not
1.32V, adjust potentiometer R34 until 1.32V is
obtained.
10) Enable the function generators. Set the clock function generator for an output amplitude of 2.4VP-P
and clock frequency ≤100MHz. Set the analog input
signal generators for an output amplitude ≤2VP-P
and to the desired input frequency. The two function
generators should be phase-locked to each other.
11) For nonmultiplexed output operation, set the logic
analyzer to capture on the clock’s rising edge. In
multiplexed output operation mode, channel A data
is presented on the falling edge and channel B data
is presented on the rising edge of the logic analyzer
clock.
12) Enable the logic analyzer.
13) Collect data using the logic analyzer.
Detailed Description
The MAX1198 EV kit is a fully assembled and tested circuit board that contains all the components necessary
to evaluate the performance of the MAX1195–MAX1198,
dual 8-bit ADCs. The MAX1195, MAX1197, and
MAX1198 are dual-output, nonmultiplexed ADCs, where
data is captured on two separate 8-bit bus lines. The
MAX1196 provides digitized data of the two input channels in multiplexed fashion on a single 8-bit bus. The EV
kit comes with the MAX1198, which can be evaluated
with a maximum clock frequency of 100MHz. The
MAX1198 accepts differential or single-ended analog
input signals. With the proper board configuration (as
Power Supplies
The MAX1198 EV kit requires separate analog and digital power supplies for best performance. A 3.3V power
supply is used to power the analog portion of the
MAX1198 and the clock signal circuit. The MAX1198
analog supply voltage has a range of 2.7V to 3.6V;
however, 3.3V must be supplied to the EV kit (VADUT,
VA) to meet the minimum input voltage supply to the
clock shaping circuit. A separate 2.5V power supply is
used to power the digital portion (VDDUT, VD) of the
MAX1198 and the buffer/driver; however, it operates
with a voltage supply as low as 1.7V and as high as
3.6V. Enhanced dynamic performance is achieved
when the digital supply voltage is lower than the analog
supply voltage.
Clock
An on-board clock-shaping circuit generates a clock
signal from a sine-wave signal applied to the CLOCK
SMA connector. The input signal should not exceed an

MAX1198 Evaluation Kit
amplitude of 2.6V P-P . The frequency of the signal
should not exceed 100MHz for the MAX1198. The clock
frequency of the sinusoidal input signal determines the
sampling frequency of the ADC. A differential line receiver (U2) processes the input signal to generate the CMOS
clock signal. The signal’s duty cycle can be adjusted with
potentiometer R34. A clock signal with a 50% duty cycle
(recommended) can be achieved by adjusting R34 until
1.32V (40% of the analog power supply) is produced
across test points TP1 and TP2 when the analog voltage
supply is set to 3.3V. The clock signal is available at the
J1-43 pin (CK), which can be used as a clock source to
the logic analyzer.
Input Signal
The MAX1198 accepts differential or single-ended analog input signals applied to channels A or B. However,
the EV kit requires only single-ended analog input signals, with an amplitude of less than 2VP-P provided by the
user. During single-ended operation, the signal is applied
directly to the ADC, while in differential mode, an onboard transformer converts the single-ended analog input
to a differential analog signal for the ADCs differential
input pins. To evaluate single-ended performance, connect the input signal to the S/E_INA (channel A) or
S/E_INB (channel B) SMA connectors. To evaluate differential performance, connect the input signal to the
D/E_INA (channel A) or D/E_INB (channel B) SMA
connectors. For single-ended or differential operation,
see Table 1 for jumper configuration.
Note: When a differential signal is applied to the ADC,
positive and negative input pins receive half of the supplied input signal, with an offset voltage of VADUT/2.
Enable/Power-Down/Sleep Modes
The MAX1198 EV kit also features jumpers that allow
the user to enable or disable functions of the data converter. Jumper JU6 controls the sleep mode, jumper
JU7 controls full power-down mode, and jumper JU8
controls the outputs enable/disable mode. See Table 2
for jumper settings.
Reference Voltage
The MAX1198 requires an input voltage reference at the
REFIN pin to set the full-scale analog signal voltage input.
The stable on-chip voltage reference of 2.048V can be
accessed at REFOUT. The EV kit was designed to use
the on-chip voltage reference by connecting REFIN to
REFOUT through resistor R20. The user can externally
adjust the reference level, and hence the full-scale range,
by installing a resistor at the R19 pad (located on the
board’s component side). The adjusted reference level
can be calculated by applying the following equation:
VREFIN =
R19
x VREFOUT
R19 + R20
where R19 is the value of the resistor installed, R20 is a
10kΩ resistor, and VREFOUT is 2.048V. Alternatively, the
user can apply a stable, low-noise, external voltage reference directly at the REFIN pad to set the full-scale range.
Digital Output Format
The MAX1198 features two 8-bit, parallel, CMOS-compatible, digital outputs (channels A and B). The digital output
coding can be chosen to be either in two’s complement
format or straight offset binary format by configuring
jumper JU5. See Table 3 for jumper configuration.
Two drivers buffer the ADC’s channel A and B digital outputs. Each buffer is able to drive large capacitive loads,
which can be present at the logic analyzer connection,
without compromising the digital output signal. The outputs of the buffers are connected to a 50-pin header (J1)
located on the right side of the EV kit, where the user can
connect a logic analyzer or data-acquisition system. See
Table 4 for channel and bit location on header J1.
