Low-Cost, Dual Sampling ADC Delivers Low Noise, High-Performance Operation to High End Applications

Compact, Dual 14-Bit, 2MSPS ADC Available in Commercial and Military Temperature Range Options

o Dual-channel, 14-bit resolution, 2MSPS sample rate
o Low cost, functionally complete compact 40-pin SMT TDIP package
o Edge-triggered operation with no pipeline delays
o Low noise: 250µV rms, 79dB SNR, -80dB THD
o No missing codes over full operating temperature range

March 10th, 2006, Mansfield, MA - C&D Technologies (NYSE: CHP) has launched a fully integrated, dual sampling, 2MSPS (mega-sample per second) 14-bit ADC (analog-to-digital converter) for high-end, dual-channel applications that demand low-noise, high-performance operation. Available in commercial and military temperature range options, the new DATEL ADSD-1402S ADC is a compact, low-power device that delivers 'no-missing-code' performance over the full operating temperature range.

The ADSD-1402S is supplied in a low-cost, functionally complete 40-pin SMT TDIP package incorporating an 'out-of-range' indicator and all of the timing and control logic necessary to operate from a single, edge-triggered 'start convert' pulse. Output data is provided with none of the pipeline delays typically associated with high-resolution monolithic multi-pass converters. Such delays cannot be tolerated in many time-critical, high-end applications.

C&D's new ADC is suitable for a wide variety of high-end medical, industrial, scientific and military imaging applications, as well as dual-channel I/Q (In-phase and Quadrature) applications used in communications, radar and sonar systems. In addition, a large-signal input bandwidth of 12MHz makes the ADSD-1402S ideal for wideband, multi-channel spectrum and FFT-based applications.

The ADSD-1402S is based on a proprietary gate array and a design that ensures excellent dynamic performance by optimizing signal return paths and providing internal, local decoupling. As a result, typical RMS noise level is rated at just 250μV, while the signal-to-noise ratio (SNR) - one of the most important specifications for imaging applications - is 80dB.

Along with all the necessary timing and control logic to operate from either single or double start convert pulses, the new ADC contains two fast-settling sample/hold amplifiers, two 14-bit ADCs, multiplexed output buffers, and a precision reference. The device operates from ±5V supplies with a power consumption of just 600mW, and is available in options for use over both the commercial (0º to 70ºC) and military (-55ºC to 125ºC) temperature ranges.

Price and Delivery
Delivery for the ADSD-1402S converters is stock to two weeks for small quantity sample orders, with production quantities from four to six weeks. Pricing for 100+ units is $195 per unit for the ADSD-1402S commercial operating temperature range ADC, and $254 per unit for the ADSD-1402S-EX military temperature range option.
