Overview
CS4121 CS4121 Low Voltage Precision Air-Core Tach/Speedo Driver Description The CS4121 is specifically designed for use with air-core meter movements.
The IC provides all the functions necessary for an analog tachometer or speedometer.
The CS4121 takes a speed sensor input and generates sine and cosine related output signals to differentially drive an air-core meter.
Many enhancements have been added over industry standard tachometer drivers such as the CS289 or LM1819.
The output utilizes differential drivers which eliminates the need for a zener reference and offers more torque.
The device withstands 60V transients which decreases the protection circuitry required.
The device is also more...
