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.

DDIP, the functionally complete ADS-119 contains

a fast-settling sample/ hold ampliﬁ er, a subranging

(two-pass) A/D converter, a precise voltage refer-

ence, timing/control logic, and error-correction
