Low noise image processing

Murata Power Solutions has introduced a new quad sampling Analog to Digital (A/D) converter for 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 10 MHz, 14-Bit dual and single A/D products. The ADSQ-1410 is a functionally complete, quad 14-Bit resolution, 10 mega samples per second (MSPS) converter. The new module has excellent dynamic performance (SNR 80dB) making it ideal for both time and multi-channel frequency domain applications.

Typical applications for the 66-pin 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 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. The new cost effective, functionally complete modules require only 5V for internal analog supplies and 2V 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. 2V 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 0C to +70C and overall package dimensions are 86.36mm x 27.94mm x 9.91mm (3.4in. x 1.1in. x 0.39in.)
