Product Summary

The AD7824KN is a high speed, multi channel, 8-bit ADC with a choice of four multiplexed analog input. A half-flash conversion technique of the AD7824KN gives a fast conversion rate of 2.5μs per channel, and the parts have a built-in track-and-hold function capable of digitizing full-scale signals of 10 kHz (157mV/μs slew rate) on all channels. The AD7824KN operates from a single 5 V supply and have an analog input range of 0 V to 5 V, using an external 5 V reference.

Parametrics

AD7824KN absolute maximum ratings: (1) VDD:0 V, 7 V; (2)Digital Input Voltage to GND(RD, CS, A0, A1, and A2): –0.3 V, VDD + 0.3 V; (3)Digital Output Voltage to GND(DB0, DB7, RDY, and INT):–0.3 V, VDD + 0.3 V; (4)VREF (+) to GND : VREF (–), VDD + 0.3 V; (5)VREF (–) to GND: 0 V, VREF (+); (6)Analog Input (Any Channel): –0.3 V, VDD + 0.3 V.
