CS4101

CS4101 CS4101 Precision Air-Core Tach/Speedo Driver with Separate Function Generator Input Description Features The CS4101 is specifically designed for use with air-core meter movements. The IC provides all the functions necessary for an analog tachometer or speedometer. The CS4101 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 CS-289 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 precise than existing devices allowing for fewer trims and for use in a speedometer. s Direct Sensor Input s High Output Torque s Low Pointer Flutter s High Input Impedance s Overvoltage Protection Absolute Maximum Ratings Supply Voltage (<100ms pulse tr...
