Quad sampling converter

Murata has introduced a quad sampling analog to digital converter for image processing where low noise performance and the ability to convert full-scale step input signals at a 10 MHz conversion rate is required.

The ADSQ-1410 builds on a product family that already includes 10 MHz, 14-bit dual and single A/D products. The converter is a functionally complete, quad 14-bit resolution, 10 MSa/s device that has good dynamic performance (SNR 80 dB) making it suitable for both time and multi-channel frequency domain applications.

Typical applications for the 66-pin SMT or TDIP through-hole packaged converter include medical imaging, radar, sonar, communications and general instrumentation. A 2.5 V precision internal reference, along with individual analog input range selection pins, provides tracking over temperature while allowing each channel to be independently configured for an analog input range of ±1 to ±2.5 V. The modules require ±5 V for internal analog supplies and 2 to 5 V supply for logic outputs.
