Chip - AC4316 Chip: Front end Chip for Dual Channel Inductive Position Encoder
AC4316 is a specialized chip for inductive position sensors, used to drive sensors and process analog sensor signals, providing differential sine and cosine output signals.

High speed position measurement based on induction principle, capable of supporting speeds up to 240000rpm (single pole to coil);
No need for magnets, high cost-effectiveness;
Can support on axis or off-axis rotation, linear and circular motion sensing;
The implementation of induction coils is flexible and can adapt to any angle range;
High precision: ≤ 0.06% @ full range (with ideal coil);
The rotation sensing range can reach 360 º angle;
Can achieve differential or single ended sine and cosine analog signal output;
Power supply voltage range: 5.0V ± 10%;
Wide working temperature range: -40 ° C~+150 ° C;
Overvoltage and reverse polarity protection: output pin ± 24V;
Integrated programmable automatic gain control function;
32 * 16 bit EEPROM stores user configuration information and can be programmed through I2C interface;
Optional programming through analog (10KHz) or digital (100KHz) I2C interface;
The internal security mechanism design of the ASIL-C standard can quickly diagnose alarms through interrupt pins (a total of 21 interrupt sources);
Passed AEC-Q100 certification (product name AC4316A16TR certified by automotive regulations)
Facilitating redundant design and improving security levels;
