The AD654JNZ from Analog Devices is a low-cost, monolithic Voltage-to-Frequency (V/F) converter. It is designed for applications requiring precise conversion of analog voltage signals into digital frequency outputs.
Key electrical specifications include a full-scale frequency of up to 500 kHz and integral nonlinearity of ±0.4% Fsr. The device operates over a wide supply voltage range, from 4.5 V to 36 V for single supply, and ±5 V to ±18 V for dual supply configurations. It draws a low quiescent current of only 2.0 mA.
The AD654JNZ features a versatile input amplifier with high input impedance and low drift, allowing direct interfacing with small signals from sources like thermocouples or strain gauges. It provides a square-wave output capable of driving up to 12 TTL loads, optocouplers, or long cables.
Packaged in an 8-lead PDIP, the AD654JNZ requires minimal external components, typically just an RC timing network and a pull-up resistor for the output stage. Its operating temperature range is -40°C to +85°C. This converter is suitable for various applications including A/D conversion, isolated signal transmission, and F/V conversion.
