AD654JRZ, Конвертер напряжение-частота, F=500 КГц [SO-8]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., Single or dual supply, Full-scale frequency up to 500kHz, Minimum number of external components needed, Versatile input amplifier, Positive or negative voltage modes, Negative current mode, High input impedance, Low power, 2mA Quiescent current, Low offset, Low drift
