Murata Power Solutions has introduced a quad sampling analogue to digital converter for image processing applications where low noise performance and the ability to convert full scale step input signals at a 10MHz conversion rate is required.
 The ADSQ-1410 converter builds on a product family that already includes 10MHz, 14Bit dual and single a/d products. The ADSQ-1410 is a functionally complete, quad 14Bit resolution, 10msps converter. The module's dynamic performance is SNR 80dB, making it suitable for both time and multi-channel frequency domain applications.
Typical applications for the 66pin SMT or TDIP through hole packaged ADSQ-1410 include medical imaging, radar, sonar, communications and general instrumentation. A 2.5V precision internal reference, along with individual analogue input range selection pins, is said to provide suitable tracking over temperature while allowing each channel to be independently configured for an analogue input range of ±1 to ±2.5V. The modules require ±5V for internal analog supplies and 2 to 5V supply for logic outputs.
The ADSQ-1410 uses a single rising edge triggered start convert signal to control the conversion of all four a/ds. 2 to 5V digital cmos outputs are multiplexed into pairs providing two parallel, three state output buses. Four independent enable control pins offer individual output data and overflow/ underflow selection.
Operating temperature range for the ADSQ-1410 is 0 to 70ºC and overall package dimensions are 86.36 x 27.94 x 9.91mm.
