Description

The ADS-119 is a high-performance, 12-bit, 10MHz sampling A/D converter.  The device samples input signals up to Nyquist frequencies with no missing codes.  It 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 error- correction 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 ±1.5V. Models are available for use in either commercial (0 to +70°C) or military (55 to +125°C) operating temperature ranges.
