11 / 12 page AD7776/AD7777/AD7778 –11– REV. 0 RTN is tied to REFOUT then the analog input range becomes 0 V to 2 V. The fixed 2 V analog input voltage span of the ADC can range from 1 V to 3 V (RTN = 0 V) to 0 V to 2 V (RTN = 2 V), i.e., with proper biasing, an input signal range from 0.3 V to 2.3 V can be covered. Both the relative accuracy and differen- tial nonlinearity performance remains essentially unchanged in this mode while the SNR and THD performance are typically 2 dB to 3 dB worse than standard. Changing the Analog Input Voltage Range By biasing the RTN pin above AGND it is possible to change the analog input voltage range from its VBIAS ± V SWING format to a more traditional 0 V to VREF range. The new input range can be described as VOFFSET to (VOFFSET + REFIN) where 0 V ≤ V OFFSET ≤ 1 V. To produce this range the RTN pin must be biased to (REFIN – 2 VOFFSET).
