LM231 V2F and F2V Series
tiThe LM231 V2F and F2V series from Texas Instruments is a voltage-to-frequency (V-to-F) and frequency-to-voltage (F-to-V) converter IC designed for precision applications. These ICs operate at a frequency of 100 kHz with a remarkable accuracy of ±0.01%, making them ideal for applications requiring high precision in signal conversion. Engineers often reach for these ICs when they need to convert analog voltages into precise digital frequencies or vice versa. They are commonly used in systems that require accurate measurement and control, such as in motor speed control, pulse-width modulation (PWM) circuits, and various sensor interfaces. For instance, in motor control applications, these converters can help in accurately measuring and controlling the speed of electric motors by converting the motor’s RPM into a corresponding frequency output. One practical observation is that the LM231 series is highly reliable and easy to integrate into existing designs due to its compact 8-pin PDIP package. This makes it a popular choice for both prototyping and production, especially in environments where space is limited. Another useful feature is its rail-to-rail input and output capability, whi
