CS8190ENF16 CS8190 AWLYYWWG AWLYYWWG CS8190 Precision Air-Core Tach/Speedo Driver with Return to Zero The CS8190 is specifically designed for use with aircore meter movements. The IC provides all the functions necessary for an analog www.onsemi.com tachometer or speedometer. The CS8190 takes a speed sensor input and generates sine and cosine related output signals to differentially drive an aircore meter. Many enhancements have been added over industry standard 20 16 tachometer drivers such as the CS289 or LM1819. The output utilizes 1 differential drivers which eliminates the need for a zener reference 1 and offers more torque. The device withstands 60 V transients which PDIP16 SO20W decreases the protection circuitry required. The device is also more NF SUFFIX DWF SUFFIX CASE 648 CASE 751D precise than existing devices allowing for fewer trims and for use in a speedometer.
