FEATURES

GENERAL 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. 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 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.
