Analog Devices AD7824LNZ 4-Channel 8-Bit ADC DIL24
Manufactured by Analog Devices - AD7824LNZ - DIL24 through hole package.
DESCRIPTION
The AD7824 is a high speed, multichannel, 8-bit ADC with four multiplexed analog inputs. A half-flash conversion technique gives a fast conversion rate of 2.5 µs per channel, and the parts have a built-in
track-and-hold function capable of digitizing full-scale signals of 10 kHz (157 mV/µs slew rate) on all channels. The AD7824 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.
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 a clock signal for the ADC. The AD7824 can be interfaced easily to most popular microprocessors.
FEATURES
- 4-channel input multiplexer gives cost effective, space-saving multichannel ADC system.
- Fast conversion rate of 2.5 µs/channel features a per-channel sampling frequency of 100 kHz for the AD7824.
- Built-in track-and-hold function allows handling of four channels up to 10 kHz bandwidth (157 mV/µs slew rate).
- Tight total unadjusted error spec and channel-to-channel matching eliminate the need for user trims.
Single 5 V supply simplifies system power requirements. - Fast, easy-to-use digital interface allows connection to most popular microprocessors with minimal external components. No clock signal is required for the ADC.
