CRCW06031M20FKEA Datasheet USING THE AD9057 Analog Inputs T he AD 905 7 provides a single-ended analog input impedance of 150 k I . T he input requires a dc bias current of 6 cc4 (typical) centered near +2.5 V (+10%). T he dc bias may be provided by the user or may be derived from the AD C 's internal voltage reference. Figure 14 shows a low cost dc bias implementation allowing the user to capacitively couple ac signals directly into the ADC without additional active circuitry. For best dynamic performance, the VREF OUT pin should be decoupled to ground with a 0.1 :itor (to minimize modulation of the refere:Ve vo'tak) 1aa.:dart:lt: bias resistor should be approxi- mately l kl . A 1 kj' esistor (+20%) is included within the AD9057 and may be used to reduce application board size and complexity.
