ADVFC32KNZ Datasheet PDF - ADI

●The ADVFC32KNZ is a monolithic Voltage-to-Frequency (V/F) Converter with good linearity (0.01% maximum error at 10kHz) and operating frequency up to 0.5MHz. In the V/F configuration, positive or negative input voltages or currents can be converted to a proportional frequency using only a few external components. For F/V conversion, the same components are used with a simple biasing network to accommodate a wide range of input logic levels. TTL or CMOS compatibility is achieved in the V/F operating mode using an open collector frequency output. The pull-up resistor can be connected to voltages up to 30V or to +15 or +5V for conventional CMOS or TTL logic levels. This resistor should be chosen to limit current through the open collector output to 8mA. A larger resistance can be used if driving a high impedance load. Input offset drift is only 3ppm of full scale per °C and full-scale calibration drift is held to a maximum of 100ppm/°C (ADVFC32BH) due to a low T.C. Zener diode.
