Page 1 of 5www.cd4power.com ADSD-1410S Dual 14-Bit, 10MSPS Sampling A/D Converter 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.

- Rated performance requires using good high-frequency cir-
and digital ground separately to the power supplies. Figure 2. ADSD-1410S Timing Diagram
- Connect the converter per Figure 3. Apply a pulse of 50
used on the outputs for calibration purposes.
- Zero (Offset) Adjustments
- Repeat above step for Analog Input B (Pin 40). Use trimpot
R2 for the zero (Offset) adjustment .
- T o confirm proper operation of the device, vary the precision
