The LM2907M-8/NOPB integrated circuit (IC) is a voltage/frequency (V/F) and frequency/voltage (F/V) converter from Texas Instruments. The LM2907M-8/NOPB is a low power, dual-supply IC that combines the features of a programmable frequency-to-voltage (F/V) converter with a programmable voltage-to-frequency (V/F) converter. The device is designed to be used in a wide range of applications, such as ac/dc power converters, motion control systems, industrial controllers, and regulators.The LM2907M-8/NOPB is an ideal choice for applications that require a low power, wide temperature range and high accuracy. The device can operate with dual supplies ranging from 5V to 15V and is capable of handling input/output signals with a maximum of 18V. The V/F and F/V conversion is controlled by means of an internally set voltage divider network and a low impedance control input (I_ctrl). Depending on the internal clock frequency, the maximum output frequency is 32kHz.The LM2907M-8/NOPB features both frequency-to-voltage and voltage-to-frequency conversion capabilities. The F/V conversion is implemented with an integrated voltage controlled oscillator (VCO) and voltage divider network, which allows for setting frequency outputs from 10 Hz to 32 kHz. The V/F conversion is achieved by means of a voltage to frequency converter (VFC). The device has a maximum input of 18V and a minimum of 0V. Additionally, the LM2907M-8/NOPB is capable of delivering up to 12mA sink current, allowing it to power a wide variety of load components.The frequency-to-voltage and voltage-to-frequency modes of the LM2907M-8/NOPB control are enabled via a logic control pin (I_ctrl). This pin is actively driven high for frequency-to-voltage conversion and low for voltage-to-frequency conversion. Additionally, the device is designed with a frequency monitor function that can be used to monitor the output frequency for noise and ripple sources. This monitor function allows the device to detect any noise or drift from the input signal and to adjust the output frequency accordingly.The LM2907M-8/NOPB is well- suited for applications with wide temperature range due to its advanced dielectric insulation system, which allows the device to tolerate up to 150°C. The device also includes a Power Good (PG) signal, which indicates whether the device is properly powered. The low-power consumption, high accuracy and precision operation make the LM2907M-8/NOPB an ideal device for applications where low-power, precise signal conversion is required.In conclusion, the LM2907M-8/NOPB is a precision V/F and F/V converter IC from Texas Instruments. The device combines the features of a programmable frequency-to-voltage converter with a programmable voltage-to-frequency converter. The device has a wide input range, up to 18V, and a low power consumption making it an ideal choice for applications requiring high accuracy and precise signal conversion. Furthermore, the device features an advanced dielectric insulation system that allows it to tolerate up to 150°C and offers an integrated Power Good signal to indicate the proper power condition.
