LM2907M - Brand New Texas Instruments Voltage-to-Frequency / Frequency-to-Voltage Converters
-
Description
The LM2907M is a voltage-to-frequency / frequency-to-voltage converter. It consists of two independent, high gain, internally frequency-compensated operational amplifiers designed specifically to operate from a single power supply over a wide range of voltages. Operation from dual power supplies is also possible, and the low power supply current drain is independent of the magnitude of the power supply voltage.
Specifications and Features
- Internally frequency-compensated for unity gain
- Large DC voltage gain: 100 dB
- Wide bandwidth (unity gain): 1 MHz (temperature-compensated)
- Wide power supply range: single supply - 3 VDC to 30 VDC, dual supplies - ±1.5 VDC to ±15 VDC
- Very low supply current drain: 400 µA (essentially independent of supply voltage)
- Low input biasing current: 45 nADC (temperature-compensated)
- Low input offset voltage: 2 mVDC, offset current: 5nADC
- Differential input voltage range equal to the power supply voltage
- Large output voltage swing: 0 VDC to V+ 1.5 VDC
Application Scenarios
The LM2907M can be used in various applications where voltage-to-frequency or frequency-to-voltage conversion is required. Some possible scenarios include:
- Signal processing
- Frequency measurement
- Frequency synthesis
- Voltage-controlled oscillators
Comparison
Advantages- Wide power supply range
