ADVFC32:  Low Cost Monolithic Voltage-to-Frequency (V/F) Converter

Product Details

The industry standard ADVFC32 is a low cost monolithic voltage-to-frequency (V/F) converter or frequency-to-voltage (F/V) converter with good linearity (0.01% max error at 10 kHz) and operating frequency up to 0.5 MHz. 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 pullup resistor can be connected to voltages up to 30 volts, or to +15 V or +5 V for conventional CMOS or TTL logic levels. This resistor should be chosen to limit current through the open collector output to 8 mA. 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 100 ppm/°C (ADVFC32BH) due to a low T.C. Zener diode.

The ADVFC32 is available in commercial, industrial, and extended temperature grades. The commercial grade is packaged in a 14-pin plastic DIP while the two wider temperature range parts are packaged in hermetically sealed TO-100 cans.
