Sampling ADCs feature noise levels to 150 µVrms.
Press Release Summary:
Analog-signal-processing (ASP), multi-chip ADSD-1410 uses active laser trimming of thin-film resistors, weaving different semiconductor chips into one ASP function. It has 2 input channels, wideband (30 MHz) sample-hold amplifiers, and independently clocked, 14-bit, 10 MSPS ADCs. Housed in 28-pin, double-DIP, ceramic package, unit employs proprietary gate array that provides timing and control logic necessary to operate each converter from one edge-triggered, start-convert pulse.

Functionally Complete Dual A/D Converters
DATEL's new ADSD-1410 is a contemporary, analog-signal-processing (ASP), multi-chip module (MCM). Technologically, the ADSD-1410 uses active laser trimming of thin-film resistors to weave different semiconductor chips-fabricated using different semiconductor processes-into a single, high-speed, ASP function that exploits the best performance features of each chip and each process technology.
Functionally, the ADSD-1410 is a dual, 14-bit, 10MHz, sampling analog-to-digital (A/D) converter with buffered outputs. It has two input channels (A and B); two wideband (30MHz) sample-hold (S/H) amplifiers; and two, independently clocked, 14-bit, 10MSPS (10 megasamples per second) A/D converters.
Single Package, Single Edge
The ADSD-1410 is housed in a single, 28-pin, double-DIP, ceramic package. The unit employs a proprietary gate array that provides all the timing and control logic necessary to operate each converter from a single, edge-triggered, start-convert pulse. Consequently, the 2 A/D's can be run independently at 10MHz each, and alternating blocks of data can be clocked from the 3-state output buffer continuously at 20MHz.
Low-Noise Means High Signal-to-Noise Ratio
Within the ADSD-1410's single-package multi-chip layout, DATEL's designers have optimized signal-return and analog/digital-ground paths ... as well as provided localized capacitive decoupling ... to obtain 150µVrms noise levels. Consequently, signal-to-noise ratio (SNR), one of the most important specifications for imaging applications, is specified at 78dB. Additionally, the use of all high-bandwidth analog components results in a THD (total harmonic distortion) spec of-80dB.
Applications
Applications for the ADSD-1410 include numerous high-end imaging applications (digital X-ray equipment, digital telescopes, military imaging, etc.) and two-channel I/Q (in-phase and quadrature) applications in communications, radar and sonar. The ADSD-1410's large-signal input bandwidth (20MHz) also makes the product an excellent choice for multi-channel, FFT-based applications such as spectrum analyzers.
Low Power Consumption ... Temperature Range Options
The ADSD-1410 consumes just 1.7 Watts from its three supply rails of ±5V and +15 Volts. The unit is specified for operation over either the commercial (0 to +70°C, "MC" models) or military (-55°C to +125°C, "MM" models) temperature ranges. Contact DATEL for military "high-rel" screening.
Price and Delivery
Delivery of small-quantity sample orders for either the ADSD-1410MC or the ADSD-1410MM is stock to 2 weeks. Production quantities require 4 to 6 weeks. Pricing is as follows:
Model Operating Temp. Range Price (500 Pieces)
