TC9400COD

The Microchip Technology TC9400COD is a low-cost, low-power CMOS integrated circuit designed for both Voltage-to-Frequency (V/F) and Frequency-to-Voltage (F/V) conversion applications. It accepts an analog input signal and generates an output pulse train with a frequency linearly proportional to the input voltage, or vice versa for F/V conversion.

Key electrical specifications include a V/F linearity of ±0.05% and an operating frequency range of DC to 100 kHz for both V/F and F/V modes. The device offers a typical power dissipation of 27 mW and can operate from single (+8V to +15V) or dual (±4V to ±7.5V) power supplies. Gain temperature stability is typically ±25 ppm/°C.

This component is housed in a 14-SOIC package and is designed for surface mounting. A complete V/F or F/V system requires only the addition of external capacitors, resistors, and a reference voltage, making it suitable for various data acquisition and signal processing tasks.

Applications for the TC9400COD include microprocessor data acquisition, analog-to-digital converters, analog data transmission and recording, phase-locked loops, frequency meters, tachometers, motor control, and FM demodulation.
