Rochester Electronics Data Acquisition - Analog to Digital Converters (ADC) AD7858BNZ

The AD7858BNZ is a high-speed, low-power, 12-bit analog-to-digital converter (ADC) designed for applications requiring efficient data acquisition. It operates from a single power supply ranging from 3 V to 5.5 V and offers a throughput rate of 200 kSPS. The device features eight single-ended or four pseudo-differential input channels, making it versatile for various signal types. The ADC includes automatic calibration on power-up, ensuring accurate performance over time and temperature. It has low power consumption, typically 12 mW at 3 V for the AD7858 version, and offers power-down modes that reduce consumption to as low as 25 µW. The AD7858BNZ supports a flexible serial interface compatible with 8051, SPI, and QSPI protocols, facilitating easy integration into existing systems. Available in multiple package options, including 24-lead DIP, SOIC, and SSOP, the AD7858BNZ is suitable for battery-powered systems, medical instruments, and instrumentation applications where low power and high performance are critical.
