+5V DIGITAL

SUPPLY

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

... To avoid interaction, offset must be adjusted before gain. The ranges of adjustment for the circuits in Figure 3 and 4 are guaranteed to compensate for the ADS-119's initial accuracy errors and may not be able to compensate for additional system errors. A/D converters are calibrated by positioning their digital outputs exactly on the transition point between two adjacent digital output codes ...
