Murata unveils A/D converter for image processing
Murata Power Solutions
ADSQ-1410
Murata Power Solutions has introduced a quad-sampling analogue-to-digital (A/D) converter for image-processing applications.
The ADSQ-1410 is suitable for use where low-noise performance and the ability to convert full-scale step input signals at a 10MHz conversion rate are required.
The converter builds on a product family that already includes 10MHz, 14-bit dual- and single-A/D products.
The ADSQ-1410 is a functionally complete converter offering 10 mega samples per second (MSPS).
The module also offers good dynamic performance (SNR 80dB), making it suitable for both time and multi-channel frequency domain applications, according to the company.
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 analogue input range selection pins, provides tracking over temperature while allowing each channel to be independently configured for an analogue input range of +/-1V to +/-2.5V.
The cost-effective modules require +/-5V for internal analogue 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.
The 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.
The operating temperature range for the ADSQ-1410 is 0C to +70C and the overall package dimensions are 86.36mm x 27.94mm x 9.91mm (3.4in x 1.1in x 0.39in).
