CS4121
Low Voltage Precision
AirCore Tach/Speedo
Driver
The CS4121 is specifically designed for use with aircore 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 aircore 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 60 V 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.
The CS4121 is compatible with the CS8190, and provides higher
accuracy at a lower supply voltage (8.0 V min. as opposed to 8.5 V). It
is functionally operational to 6.5 V.

Maximum ratings are those values beyond which device damage can occur.
Maximum ratings applied to the device are individual stress limit values (not
normal operating conditions) and are not valid simultaneously. If these limits
are exceeded, device functional operation is not implied, damage may occur
and reliability may be affected.
