The ADS-951 is an 18-bit, 1MHz sampling A/D converter. This device accurately samples full-scale input signals up to Nyquist frequencies with no missing codes. This feature, combined with excellent signal-to-noise ratio (SNR) and total harmonic distortion (THD), makes the ADS-951 the ideal choice for both time-domain (medical imaging, scanners, process control) and frequency-domain (radar, telecommunications, spectrum analysis) applications.
Packaged in a 32-pin, side-brazed, metal-sealed, ceramic TDIP, the functionally complete ADS-951 contains a fastsettling sample-hold amplifier, a subranging (two-pass) A/D converter, an internal reference, timing/control logic, and errorcorrection circuitry. Digital input and output levels are TTL, and the ADS-951 only requires the rising edge of the start convert pulse to operate.
Requiring ±15V and ±5V supplies, the ADS-951 typically dissipates 1.45 Watts. ADS-951 is offered with a bipolar (±5V) analog input range. Models are available for use in either commercial (0 to +70°C) or extended (40 to +110°C)
