90dB SFDR
for digitizing high frequency, wide dynamic range signals. n Low Power: 88mW/59mW/46mW per Channel AC performance includes 73dB SNR and 90dB spurious n Single 1.8V Supply free dynamic range (SFDR). Low power consumption per n Serial LVDS Outputs: 1 or 2 Bits per Channel channel reduces heat in high channel count applications. n Selectable Input Ranges: 1V Integrated bypass capacitance and flowthrough pinout P-P to 2VP-P n 800MHz Full Power Bandwidth S/H reduces overall board space requirements. n Shutdown and Nap Modes DC specs include ±1LSB INL (typ), ±0.3LSB DNL (typ) n Serial SPI Port for Configuration and no missing codes over temperature. The transition n Internal Bypass Capacitance, No External noise is a low 1.2LSBRMS.
