Rochester Electronics Data Acquisition - Analog to Digital Converters (ADC) AD7876CR

The AD7876CR is a 12-bit analog-to-digital converter (ADC) designed for high-speed data acquisition applications. It features a track-and-hold amplifier with a 2 Oºs acquisition time and an 8 Oºs conversion time, enabling it to handle input signals with a frequency of up to 50 kHz. The device operates with a bipolar input voltage range of ¬±10 V and is powered by ¬±5 V supplies, consuming a typical power of ,àí60 mW. This ADC includes an on-chip reference and a laser-trimmed clock, eliminating the need for external timing components. It supports multiple data output formats, including parallel, byte, and serial interfaces, with a fast data access time of 57 ns, making it compatible with modern microprocessors and digital signal processors. The AD7876CR is specified for dynamic performance parameters such as signal-to-noise ratio (SNR) of 72 dB at 10 kHz input frequency, ensuring reliable performance in various applications. The device is available in a 24-pin small outline (SOIC) package, suitable for space-constrained designs. Overall, the AD7876CR is a robust choice for engineers seeking a reliable and efficient ADC for their data acquisition needs.
