- Description: AD654 Monolithic V/F Converter
AD654JNZ AD654JN AD654 Low Cost Monolithic V/F Voltage To Frequency Converter IC DIP-8 Converter IC Dual In Line Package Electrical Circuitry & Parts
The AD654 is a monolithic V/F 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 500 kHz and any FS input voltage up to Ā±30 V. Linearity error is only 0.03% for a 250 kHz FS, and operation is guaranteed over an 80 dB dynamic range.The overall temperature coefficient (excluding the effects of external components) is typically Ā±50 ppm/Ā°C. TheAD654 operates from a single supply of 5 V to 36 V and consumes only 2.0 mA quiescent current.
The low drift (4 ĀµV/Ā°C typ) input amplifier allows operation directly from small signals such as thermocouples or strain gauges while offering a high (250 M(ohm)) input resistance. Unlike most V/F converters, the AD654 provides a square-wave output, and can drive up to 12 TTL loads, optocouplers, long cables, or similar loads.
