66-pin SMT or TDIP package
Developed for image processing applications
Ideal for both time and frequency domain
applications
The ADSQ-1410 is a quad 10MSPS sampling
A/D optimized for applications where low noise
performance and the ability to convert full-scale
step input signals at a 10 MHz conversion rate are
required. With excellent dynamic performance up
to Nyquist frequencies, the ADSQ-1410 is also an
ideal choice for multi-channel, frequency domain
applications.
This functionally complete quad A/D uses a single
rising edge triggered Start Convert signal to control
the conversion cycles of all four A/D’s. The digital
CMOS outputs are multiplexed into pairs providing
two parallel, 3-state output buses. Four indepen-
dent Enable Control pins offer individual output
data and overow/underow selection.
A 2.5V precision internal reference, along with indi-
vidual analog input range selection pins, provides
ideal tracking over temperature while allowing
each channel to be independently congured for an
analog input range of ±1V to ±2.5V.
Available in both surface-mount and through-hole
packages, the ADSQ-1410 requires only ±5V for
internal analog supplies and 2V to 5V supply for logic
outputs. Typical power dissipation is 2.7 Watts.
Common applications include medical imaging,
radar, sonar, communications and instrumentation.
