Overview: ADS-944
14-Bit, 5MHz Sampling A/D Converters PRODUCT OVERVIEW
The low-cost ADS-944 is a high-performance, 14-bit, 5MHz sampling A/D converter. This device accurately samples fullscale input signals up to Nyquist frequencies with no missing codes. The dynamic performance of the ADS-944 has been optimized to achieve a THD of –77dB and a SNR of 76dB.
Packaged in a small, 32-pin TDIP, the functionally plete ADS-944 contains a fast-settling sample-hold amplifier, a subranging (two-pass) A/D converter, an internal reference, timing and control logic, three-state outputs, and errorcorrection circuitry. Digital input and output levels are TTL.
Requiring ±15V, +5V and –5.2V supplies, the ADS-944 typically dissipates 2.95 Watts. The unit is offered with a bipolar input range of ±1.25V. Models are available in mercial (0 to +70°C), industrial (–40 to +100°C), or HI-REL (–55 to +125°C) operating temperature ranges. Typical applications include radar signal analysis, medical/ graphic imaging, and FFT spectrum analysis.
