The AD654JRZ-REEL7 is a high-performance, monolithic V/F (voltage-to-frequency) converter designed for a wide range of applications. It consists of an input amplifier, a precision oscillator system, and a high-current output stage. This converter allows for the setting of any full-scale (FS) frequency up to 500 kHz and any FS input voltage up to ±30 V with a simple RC network.
At a full-scale frequency of 250 kHz, the AD654JRZ-REEL7 exhibits a linear error of only 0.03%, ensuring a high dynamic range of 80 dB. The overall temperature coefficient, excluding the influence of external components, is typically ±50 ppm/°C. The device operates from a single supply voltage ranging from 5 V to 36 V, with a low static current consumption of only 2.0 mA.
The input amplifier of the AD654JRZ-REEL7 features low drift (typically 4 µV/°C) and can directly handle small signals from sources such as thermocouples or strain gauges, while providing a high input impedance of 250 MΩ. Unlike most V/F converters, the AD654JRZ-REEL7 offers square wave outputs, capable of driving up to 12 TTL loads, optocouplers, long cables, or similar loads.
The AD654JRZ-REEL7 is packaged in a compact SOIC-8 form factor, making it suitable for integration into high-density circuit boards. Its low cost, low power consumption, and multifunctional input amplifier (supporting positive or negative voltage modes, negative current mode, and high input impedance with low drift) make it an ideal choice for various applications requiring precise voltage-to-frequency conversion.
Overall, the AD654JRZ-REEL7 combines high performance, compact packaging, and versatility to meet the demands of modern electronic systems and applications.
