Texas Instruments V/F and F/V Converters VFC32KU

The VFC32KU is a voltage-to-frequency and frequency-to-voltage converter from Quarktwin Technology Ltd. It operates effectively up to 500 kHz with excellent linearity, achieving a maximum error of 0.01% at 10 kHz and 0.05% at 100 kHz. The device features a digital open-collector frequency output compatible with common logic families, and it can be configured for either V/F or F/V conversion. The input can accept both voltage and current, providing flexibility for various applications such as integrating A/D converters, isolated data transmission, and motor speed control. The VFC32KU is available in a 14-pin SOIC package and supports a temperature range from 0¬8C to 70¬8C. It requires external components for setting the full-scale output frequency, which can be adjusted over a wide range. The device also offers good noise immunity and low nonlinearity, making it suitable for precision applications.
