Rochester Electronics Data Acquisition - Analog to Digital Converters (ADC) AD7828LRS

The AD7828LRS is an 8-channel, 8-bit analog-to-digital converter (ADC) designed for high-speed data acquisition applications. It features a fast conversion rate of 2.5 µs per channel, allowing for a sampling frequency of up to 50 kHz. The device includes a built-in track-and-hold function that can handle signals with a bandwidth of 10 kHz and a slew rate of 157 mV/µs. Operating from a single 5 V supply, the AD7828LRS has an analog input range of 0 V to 5 V and offers a low power dissipation of approximately 50 mW. The ADC is fabricated using a linear compatible CMOS process, ensuring reliable performance. It supports a simple microprocessor interface with standard Chip Select (CS) and Read (RD) signals, eliminating the need for an external clock signal. The device is characterized by tight error specifications, with a total unadjusted error of ±1/2 LSB, and minimal channel-to-channel mismatch, making it suitable for applications where precision is critical. The AD7828LRS is available in a 28-lead surface-mount package, facilitating integration into compact designs.
