Rochester Electronics Data Acquisition - Analog to Digital Converters (ADC) AD674BBR

The AD674BBR is a 12-bit successive-approximation analog-to-digital converter (ADC) designed for high-speed data acquisition applications. It features a maximum conversion time of 15 µs and is compatible with both 8-bit and 16-bit microprocessor interfaces. The device supports multiple input ranges, including ±5 V, ±10 V, 0 V to 10 V, and 0 V to 20 V, making it versatile for various applications. This ADC includes an on-chip high-precision voltage reference and clock, requiring only power supplies and control signals for operation. The AD674BBR is designed using Analog Devices' BiMOS II process, which integrates high-performance bipolar analog circuitry with digital CMOS logic. It offers minimized offset, linearity, and scaling errors through active laser trimming. The device is available in a 28-lead plastic SOIC package and is specified for operation over a temperature range of -40°C to +85°C. It also includes versions compliant with MIL-STD-883 for military applications. The AD674BBR's combination of speed, precision, and flexibility makes it suitable for a wide range of data acquisition tasks in commercial, industrial, and military environments.
