DEMO MANUAL DC200
HIGH SPEED ADC
LTC1416 (400ksps) and
LTC1419 (800ksps) 14-Bit
A/D Converter Demo Board
DESCRIPTIO
U
matic, parts list, drawings and dimensions of all the PC
board layers are included. An explanation of the layout and
bypass strategies used in this board is also included, so
that anyone designing a PC board using the LTC1416/
LTC1419 will be able to get the maximum performance
from the device. The LTC1416/LTC1419 are intended for
applications in telecommunications, digital signal pro-
cessing, imaging, or any high speed, high resolution data
acquisition application. Gerber files for this circuit board
are available. Call the LTC factory.
Some key features of this demo board include:
•
Proven 400ksps (LTC1416) and 800ksps (LTC1419)
14-bit ADC surface mount layout
•
Actual ADC footprint is only 0.5 inch
2
including
bypass capacitors
•
80dB SINAD and 90dB THD at 200kHz (LTC1416) and
80dB SINAD and 86dB THD at 400kHz (LTC1419)
inputs
The LTC
1416/LTC1419 are, respectively, 2µs, 400ksps
and 1µs, 800 ksps sampling A/D converters. The LTC1416
draws 70mW and the LTC1419 draws 150mW. The
LTC1416/LTC1419 demo board provides the user with a
way to evaluate the LTC1416 and LTC1419 high speed
A/D converters. In addition, the LTC1416/LTC1419 demo
board is intended to illustrate the layout and bypassing
techniques required to obtain optimum performance from
these parts. The LTC1416/LTC1419 demo board is de-
signed to be easy to use and requires only ±7V to ±15V
supplies, a conversion-start signal and an analog input
signal (single-ended or differential). As shown in the
Board Photo, the LTC1416/LTC1419 are very space effi-
cient solutions for A/D users. By combining a 14-bit A/D,
sample-and-hold and reference into a single SSOP pack-
age, all the data acquisition circuitry, including the bypass
capacitors, can be placed in an area of only 0.5 inch
2
.
This manual describes how to use the demo board.
Included are timing diagrams, power supply requirements
and analog input range information. Additionally, a sche-
, LTC and LT are registered trademarks of Linear Technology Corporation.

QUICK START GUIDE
This demonstration board is easily set up for evaluating
the LTC1416/LTC1419. Follow the procedure below for
proper operation.
1. Connect a –7V to –15V supply (J1), 7V to 15V supply
(J3), 0V or ground (J2), input test signal generator
(J4) and conversion clock source (J7) to the board as
shown in Figure 1. As delivered, the board is config-
ured for a ±2.5V input referenced to ground (JP2 and
JP4 are shorted). Differential inputs can be converted
by removing the shorting connector on JP4. The
demonstration board also includes an LT1363 input
buffer amplifier operating with a gain of 1. The input
signal can be buffered by removing the shorting
connector from JP2 and placing it on JP3.
2. The LTC1416/LTC1419 demo board includes an input
filter with a cutoff frequency of 1.56MHz. For lower
input frequencies, best results are obtained by using
an optional filter. The TTE J3449-100k-500-20 is a
P1-P3P4-P6P7-P8
