A/D Converter targets image processing applications.

Press Release Summary:

DATEL Quad Sampling A/D converter, Model ADSQ-1410, is 14-bit, 10 MS/sec unit that converts full-scale step input signals at rate of 10 MHz. It offers 0.5 LSB RMS DC noise and dynamic performance of 80 dB, suiting it for time and multichannel frequency domain applications. Rising edge triggered start convert signal controls conversion of all 4 converters. Unit requires ±5 V for internal analog supplies and 2-5 V supply for logic outputs and operates in temperatures from 0-70°C.

Original Press Release:

DATEL Quad Sampling A/D Converter Combines Low Noise and Excellent Dynamic Performance for a Wide Range of Image Processing Applications

o Functionally complete, quad 14-Bit, 10 MSPS A/D converter

o 0.5 LSB RMS DC noise with no missing codes

o Excellent dynamic performance with SNR of 80dB

o Choice of SMT or TDIP through-hole packages

Murata Power Solutions has introduced a new quad sampling Analog to Digital (A/D) 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 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 0°C to +70°C and overall package dimensions are 3.4in. x 1.1in. x 0.39in. (86.36mm x 27.94mm x 9.91mm)

Pricing in OEM volume is approximately $215. Sample quantities are available from the shelf. Production lead-times can range from 12-15 weeks.
