RC4152
Overview
The RC4152 is a monolithic circuit containing all of the active components needed to build a complete voltage-tofrequency converter. Circuits that convert a DC voltage to a pulse train can be built by adding a few resistors and capacitors to the internal comparator, one-shot, voltage reference, and switched current source.
- Single supply operation Pulse output DTL/TTL/CMOS compatible Programmable scale factor (K) High noise rejection Inherent monotonicity Easily transmittable output Simple full scale trim Single-ended input, referenced to ground V-F or F-V conversion Voltage or current input Wide dynamic range
- Signal isolation: - VFC-opto-isolaton-FVC - ADC with opto-isolation
- Signal encoding: - FSK modulation/demodulation - Pulse-width modulation
- Frequency scaling
- DC motor speed control
