Voltage to Frequency Converters

Description
ADI has the widest range of voltage to frequency converters (VFCs) for the instrumentation, industrial and automation markets. They are ideally suited for use in analog-to-digital conversion (ADC), long term integration, linear frequency modulation and demodulation, and frequency-to-voltage conversion. ADI’s latest family of VFCs, the AD774x series, is based on sigma-delta technology and provides high linearity in tiny packages at low cost.
