Product Description

The AD654JRZ is a Monolithic Voltage to Frequency Converter consisting of an input amplifier, a precision oscillator system and a high current output stage. A single RC network is all that is required to set up any full scale (FS) frequency up to 500kHz and any FS input voltage up to ±30V. Linearity error is only 0.03% for a 250kHz FS and operation is guaranteed over an 80dB dynamic range. The overall temperature coefficient (excluding the effects of external components) is typically ±50ppm/°C. The converter operates from a single supply of 5 to 36V and consumes only 2.0mA quiescent current. The low drift (4µV/°C typical) input amplifier allows operation directly from small signals such as thermocouples or strain gauges while offering a high (250MR) input resistance. Unlike most V/F converters, the AD654 provides a square-wave output and can drive up to 12 TTL loads, opto couplers, long cables or similar loads.
