Chip introduction

Hs0816 is a specialized wireless receiving chip, which can be used to demodulate ask/ook modulated high-frequency wireless signals, and its working frequency ranges from 300MHz-450MHz,  therefore the receiving frequency bandwidth is greater than 150MHz. This chip realizes data in and data out, and it consists of low-noise amplifier, band-pass filter, peak detection circuit, low-pass filter and comparator. The application circuit of this chip is simple, and the wireless signal receiving function can be realized with few components.

The chip can be applied to the solution to remote control duplicators.

Performance parameter

       • VDD：2.0V-3.6V

       • IDD：2.5mA

       • Receiving sensitivity：-20dBm

       • Working bit rate ：5Kbps

SOT23-5 package，always enable the receiver after power on

SOP8 package，the shutdown pin enable the receiver after power on

Advantages

1.Longer copy distance

2.Better stability

       At present, the voltage of output signal is not stable in the  double transistors circuit solution in the market, which depends on the distance between transmitters and receivers,  and it easily makes data error and copy failure when the output voltage is near the IO threshold voltage of MCU. And also consistency of transistors is required in mass production. The output voltage of HS0816  is always same with VDD, and the voltage is stable and not easy to make mistakes.

3.Simple circuit and easy debugging

       Hs0816 can work well by adjusting only one inductor. Double transistors circuit  solution has high requirements for PCB layout, design of antenna, consistency of transistors and other components, and it is difficult to debug.
