The AD7824 and AD7828 are high speed, multichannel, 8-bitADCs with a choice of four (AD7824) or eight (AD7828) multiplexed analog inputs. A half-flash conversion technique gives a fast conversion rate of 2.5 t,s per channel, and the parts have a built-in track-and-hold function capable of digitizing full-scale signals of10 kHz (157 mV/t,s slew rate) on all channels. The AD7824 and AD7828 operate from a single 5 V supply and have an analog input range of 0 V to 5 V, using an external 5 V reference. Microprocessor interfacing of the parts is simple, using standard Chip Select ( CS) and Read (RD) signals to initiate the conversion and read the data from the three-state data outputs. The half-flash conversion technique means that there is no need to generate aclock signal for the ADC. The AD7824 and AD7828 can be interfaced easily to most popular microprocessors. The AD7824 and AD7828 are fabricated in an advanced, all ion-implanted, linear compatible CMOS process (LC 2MOS) and have low power dissipation of 40 mW (typ). The AD7824 is available in a 0.3" wide, 24-lead "skinny" DIP, while the AD7828 is available in a 0.6" wide, 28-lead DIP and in 28-terminal surface-mount packages.
