Application

Input voltage (withstand voltage): it refers to the voltage range of 78L33 Vin. If the input voltage is higher than the maximum working voltage of 78L33, it will exceed the voltage withstand degree and damage. If the input voltage is lower than the minimum working voltage of 78L33, then 78L33 will not work properly.
Many engineers in the choice of BOOST type DC-DC chip found that even if the chip with the enable function, still can not turn off the system, the output voltage or follow the input voltage exists, at this time the consumption current follows the load changes, in this state will not only continue to consume power, but also the risk of damage to the post-stage circuit.
RS485 circuit is a common serial communication interface standard, widely used in industrial control environment. It uses balanced transmission and differential reception, has the ability to suppress common-mode interference, is suitable for the communication distance from tens of meters to thousands of meters, and performs well in multi-node systems.
SSP1220 is a precision 24-bit analog-to-digital converter developed and designed by Siproin Microelectronics. The SSP1220 is capable of performing conversions at sampling data rates up to 2k SPS and is stable within a single cycle. For industrial applications in noisy environments, the digital filter provides both 50Hz and 60Hz rejection at a sampling frequency of 20SPS.
