Vollgo VG590

VG590 is a special integrated circuit for superheterodyne reception. It is a single-chip solution for ASK/OOK (ON-OFF Keyed) wireless reception. This chip realizes data input and data output. It integrates a low-noise amplifier, mixer, frequency synthesizer PLL, intermediate frequency amplifier, bandpass filter, peak detection circuit, low-pass filter and comparator. The application circuit of this chip is simple and only a few components are needed to realize the wireless signal reception function. The chip demodulates the received RF signal and outputs a CMOS level data signal, achieving "data in, data out". The chip's operating voltage is 2.8~5.5V, and the current consumption is 5.2mA (433.92MHz) at 5V. The typical sensitivity can reach up to -115dBm. The maximum data rate is 10Kbit/s, and the operating temperature range is -30°C to +85°C. This chip solution is mainly suitable for systems that require simple structure and small scale in industrial and consumer fields.
