RC4151 is a power management IC from ON Semiconductor.
The document describes the 4A4151 and 4A7151 as monolithic building blocks used to convert DC voltage into digital pulses. The frequency of the output pulses is proportional to the DC input voltage. The 4A7151 variant includes a high-performance operational amplifier on the same chip, offering improved system performance over the standard 4A4151.
| Supply Voltage Range | +8 V to +30 V (Single Supply) |
|---|---|
| Linearity | Typically 0.05% |
| Temperature Stability | Typically 100 ppm/°C |
The 4A7151 includes a high performance operational amplifier on the same chip, whereas the 4A4151 does not.
It can be used to construct voltage-to-frequency converters (VFC), frequency-to-voltage converters (FVC), or other circuit functions.
