... The low-cost ADS-944 is a high-performance, 14-bit, 5MHz sampling A/D converter. This device accurately samples full- scale input signals up to Nyquist frequencies with no missing codes. The dynamic performance of the ADS-944 has been optimized to achieve a THD of –77dB and a SNR of 76dB. Packaged in a small, 32-pin TDIP, the functionally complete ...

... To avoid interaction, always adjust offset before gain. 3. Pin 8 (COMP. BITS) selects the ADS-944's digital output coding. When a logic "1" is applied to pin 8, the output coding is complementary offset binary. When pin 8 has a logic " ...
