iC-LNB 18-BIT OPTO ENCODER

WITH SPI AND SER/PAR INTERFACES

Rev A1, Page 1/35

FEATURES

APPLICATIONS

♦ System-on-chip design for excellent reliability

♦ Leading/trailing sampling of 10 binary tracks pitched at 400 µm

♦ Analog sine/cosine scanning with enlarged photodiodes,

signal conditioning and fast 8-bit vector-tracking interpolation

♦ Absolute singleturn resolution of up to 18 bit

♦ Unique FlexCount^®circuit: freely selectable resolution for

absolute and incremental data

♦ Optical position sensors

♦ Linear scales

♦ Absolute rotary encoders

♦ Programmable incremental

encoders

♦ Motor feedback systems

♦ Incremental quadrature outputs with 1 to 65,536 CPR and

programmable index signal

PACKAGES

♦ LED illumination control by 50 mA high-side current source

(sin²+cos²or sum control modes)

♦ Alarm indication for conﬁguration or illumination error

♦ Permanent RAM monitoring by parity bits

♦ 3.3 V-compatible SPI and I/O ports for conﬁguration and data

♦ Serial data readout in 1 µs cycles at 16 MHz clock frequency

♦ Parallel position data output for 16 bit

30-pin optoBGA

7.6 mm x 7.1 mm x 1.6 mm

♦ Operation at 4 V to 5.5 V within -40 °C to 110 °C

♦ 30-pin optoBGA or 38-pin optoQFN package for SMT

♦ Illumination: iC-SN85 BLCC SN1C (850 nm encoder LED)

♦ Code discs: LNB1S 42-1024 (1024 PPR, ∅ 42 mm/18 mm),

LNB4S 26-1024 (1024 PPR, ∅ 26.0 mm/9.6 mm)

38-pin optoQFN

7.0 mm x 5.0 mm x 0.9 mm
