The ADS-927 is a high-performance, 14-bit, 1MHz sampling A/D converter. This device samples input signals up to Nyquist frequencies with no missing codes. The ADS-927 features outstanding dynamic performance including a THD of 80dB. Housed in a small 24-pin DDIP or SMT (gull-wing) package, the functionally complete ADS-927 contains a fast-settling sample-hold amplifier, a subranging (two-pass) A/D converter, a precise voltage reference, timing/control logic, and errorcorrection circuitry. Digital input and output levels are TTL.
Requiring ±15V (or ±12V) and +5V supplies, the ADS-927 dissipates only 1.95W (1.65W for ±12V), maximum. The unit is offered with a bipolar input (5V to +5V). Models are available for use in either commercial (0 to +70°C) or military (55 to +125°C) operating temperature ranges. Applications include radar, sonar, spectrum analysis, and graphic/medical imaging.
