Product Summary

The AD654JN is a monolithic V/F converter consisting of an input amplifier, a precision oscillator system, and a high current output stage. The AD654JN operates from a single supply of 5 V to 36 V and consumes only 2.0 mA quiescent current. The low drift (4 μV/℃ typ) input amplifier allows operation directly from small signals such as thermocouples or strain gauges while offering a high (250 MΩ) input resistance. Unlike most V/F converters, the AD654JN provides a square-wave output, and can drive up to 12 TTL loads, optocouplers, long cables, or similar loads.

Parametrics

AD654JN absolute maximum ratings: (1)Total Supply Voltage +VS to –VS: 36 V; (2)Maximum Input Voltage:300 mV to +VS; (3)Maximum Output Current:Instantaneous: 50 mA, Sustained:25 mA; (4)Logic Common to –VS:–500 mV to (+VS –4); (5)Storage Temperature Range:–65℃ to +150℃.
