Optek / TT Electronics FS210/FS310 FlexSense® I-Series Encoders

Optek / TT Electronics FS210/FS310 FlexSense® I-Series Encoders have an optical sensor array that operates with a wide range of code wheel diameters. This includes linear strips, and resolutions. The programmable sensor is packaged standalone in a compact OptoQFN package for the FS210, and a near-IR LED is combined with the sensor in the same package for the FS310.

Features

  • Incremental optical encoder sensor IC in 32-pin 5mm x 5mm x 0.65mm OQFN package
  • Both transmissive (FS210) and reflective (FS310) variants are 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
  • 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
  • Compatible with a 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
  • 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 a 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
