Product Overview

ADVFC32 is an industry standard, low cost monolithic voltage-to-frequency (V/F) converter or frequency-to-voltage (F/V) converter with good linearity (0.01% max 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. 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. It uses a charge balancing circuit technique which is well suited to high accuracy voltage-to-frequency conversion. The full-scale operating frequency is determined by only one precision resistor and capacitor.
  • Inexpensive ±20% resistors/capacitors can be used without affecting linearity or temperature drift
  • Easily configured to satisfy a wide range of system requirements
  • Intended as a pin-for-pin replacement for VFC32 devices from other manufacturers
  • 6 decade dynamic range, voltage or current input
  • Reliable monolithic construction
  • Full-scale frequency range from 0 to 500KHz (typical at 25°C with VS= 15V)
  • Current input range from 0 to 0.25mA (typical at 25°C with VS= 15V)
  • Quiescent current is 8mA max (typical at 25°C with VS= 15V)
  • Operating temperature range from –25 to +85°C
  • 14-pin plastic DIP package
