ADS-883

® ® ADS-929 14-Bit, 2MHz, Low-Power Sampling A/D Converters FEATURES 14-bit resolution 2MHz sampling rate No missing codes Functionally complete Small 24-pin DDIP or SMT package Low power, 1.7 Watts Operates from ±15V or ±12V supplies Edge-triggered; No pipeline delays Bipolar ±5V input range GENERAL DESCRIPTION The ADS-929 is a high-performance, 14-bit, 2MHz sampling A/D converter. This device samples input signals up to Nyquist frequencies with no missing codes. The ADS-929 features outstanding dynamic performance including a THD of –79dB. Housed in a small 24-pin DDIP or SMT (gull-wing) package, the functionally complete ADS-929 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-929 typically dissipates 1.7W (1.4W for ±12V). 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.
