The device samples input signals up to Nyquist frequencies with no missing codes. The ADS-119 features excellent dynamic performance including a typical SNR of 69dB. Packaged in a metal-sealed, ceramic, 24-pin DDIP, the functionally complete ADS-119 contains a fast-settling sample/ hold amplifier, a subranging (two-pass) A/D converter, a precise voltage reference, timing/control logic, and errorcorrection circuitry. All timing and control logic operates from the rising edge of a single start convert pulse. Digital input and output levels are TTL. Requiring only ±5V supplies, the ADS-119 typically dissipates 1.8 Watts. The unit offers a bipolar input range of ±...
