HS0832 is a specialized superheterodyne integrated circuit. It is a single chip solution for ASK/OOK(on-off Keyed) wireless reception. The chip achieves data in and data out. The chip consists of low noise amplifier, mixer, frequency synthesizer PLL, if amplifier, 5^th order band pass filter, peak detection circuit, 2th order low pass filter and switch capacitor resistance comparator. The application circuit of the chip is simple, requiring very few components to receive signal.

The chip will demodulated the received RF signal, and output CMOS level data signal, which achieves "data in, data out". The operating voltage of the chip is 3.3-5.5V, the operating current is 5mA (315MHz) at 5V, and the typical sensitivity is better than -108dBm. Maximum bit rate is 10Kbit/s and operating temperature ranges from -30℃ to +85℃.

This chip solution mainly applies to the simple structure and small system in the industrial and consumer fields.
