ADSD-1410S Datasheet, PDF (1/5 Pages) C&D Technologies – Dual 14-Bit, 10MSPS Sampling A/D Converter
FEATURES
• 14-bit resolution; 10MSPS sampling rate
• Functionally complete; ±2.5V input range
• No missing codes over full temperature range
• Edge-triggered
• ±5V supplies, 1.6 Watts
• 76dB SNR, –83dB THD
• Ideal for both time and frequency
domain applications
GENERAL DESCRIPTION
The ADSD-1410S is a functionally complete, dual 14-bit,
10MSPS, sampling A/D converter. Its standard, 40-pin,
triple-wide SMT DIP contains two fast-settling sample/hold
amplifiers, two 14-bit A/D converters, multiplexed output
buffers, a precision reference, and all the timing and control
logic necessary to operate from either two or a single start
convert pulse.
The ADSD-1410S is optimized for wideband frequency-
domain applications and is fully FFT tested. The ADSD-
1410S requires only ±5V supplies and typically consumes
1.6 Watts. The digital output power supply is capable of
directly driving 5V or 3V logic systems. Models are available
in either commercial 0 to +70°C or military -55 to +125°C
operating temperature ranges.
