Product Summary

The AD6549BCPZ-RL 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 ± 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 ±50 ppm/℃. The AD6549BCPZ-RL operates from a single supply of 5 V to 36 V and consumes only 2.0 mA quiescent current. The low drift (4 mV/℃ typ) input amplifier allows operation directly from small signals such as thermocouples or strain gauges while offering a high (250 MW) input resistance. Unlike most V/F converters, the AD6549BCPZ-RL provides a square-wave output, and can drive up to 12 TTL loads, optocouplers, long cables, or similar loads.
