• 93dBSNR,-110dBTHD,112dB SFDR The ADS8471 is an 16-bit, 1-MSPS A/D converter
• ZeroLatency with an internal 4.096-V reference and a
• LowPower: 220mWat1MSPS pseudo-bipolar, unipolar input. The device includes a
16-bit capacitor-based SAR A/D converter with
• UnipolarInputRange:0V toV
ref inherent sample and hold. The ADS8471 offers a full
• OnboardReference 16-bit interface or an 8-bit bus option using two read
• OnboardReferenceBuffer cycles.
• High-SpeedParallelInterface The ADS8471 is available in a 48-lead 7x7 QFN
• WideDigitalSupply2.7V ~5.25V package and is characterized over the industrial
–40(cid:176) Cto 85(cid:176) Ctemperaturerange.
