Quad sampling A/D converter from MurataPS combines low noise and excellent dynamic performance for a wide range of image processing 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 independent Enable Control pins offer individual output data and overflow/underflow selection.

A 2.5V precision internal reference, along with individual analog input range selection pins, provides ideal tracking over temperature while allowing each channel to be independently configured 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.
