AD7821KRZ

AD7821 is a high speed, 8bit, sampling, analog-to-digital converter that offers improved performance over the popular AD7820. The AD7821 has a built-in track-and-hold function capable of digitizing full-scale signals up to 100KHz max. It also uses a half-flash conversion technique that eliminates the need to generate a CLK signal for the ADC. The AD7821 is fabricated in Linear Compatible CMOS (LC²MOS), an advanced, mixed technology process combining precision bipolar circuits with low power CMOS logic. The part features a low power dissipation of 50mW.
