FlexSense®I-Series Programmable Incremental Encoder FS210/FS310 Datasheet
The FS210/FS310 contains a revolutionary optical sensor array that can be programmed to operate with a wide range of code-wheel diameters, including linear strips, and resolutions. This programmable sensor is packaged standalone in a compact Opto-QFN package for the FS210, and a near-IR LED is combined with the sensor in the same package for the FS310. With unparalleled flexibility and versatility in a robust, subcompact package, with closed-loop LED driver control, with on-chip interpolation, and with support for automated alignment and configuration, the FlexSenseTMproducts redefine flexibility.
●Features and Benefits：
■Incremental optical encoder sensor IC in 32-pin 5mm x 5mm x 0.65mm OQFN package
■Both transmissive (FS210) and reflective (FS310) variants available.
■User-programmable, high-resolution photosensor pixel array enables quick customization and improves time-to-market.
◆Customizable quadrature-and index-track dimensions
◆Analog or digital quadrature-track output
■Compatible with code-wheel resolution of up to 1,200 lines per inch, or 4,096 PPR at a 15mm optical radius
■Programmable auto-configuration simplifies assembly and alignment.
■Closed-loop LED drive control
■IR LED embedded in the same package(FS310 only)
■Diagnostic functionality:
◆High-temperature fault (with interrupt signaling feedback)
◆LED-drive control loop out of regulation (with interrupt signaling feedback)
◆Power-on reset (with interrupt signaling feedback)
◆Code-wheel eccentricity
■I²C interface
■-40°C to +125°C ambient operating temperature
■On-chip quad-track interpolation (2x, 4x, 8x) and division (by powers of 2 up to 2,048)
■Quad-track output characteristics at native frequency up to 400kHz:
◆THD ≤ 1.0% on analog outputs
◆Transient noise ≤ 1.0% of signal amplitude on analog outputs at 40mW/cm2 input power density
◆Angular position accuracy ±1 part in 100K, or about 12 arc-seconds at 1,500 PPR, on digital outputs
■Single-supply (3.3V ± 10%) operation
