iC-MN 25-BIT NONIUS ENCODER
WITH 3-CH. SAMPLING 13-BIT Sin/D INTERPOLATION
Rev D1, Page 1/59
FEATURES
o 3 chan. simultaneous sampling 13 bit sine-to-digital conversion
o Differential and single-ended PGA inputs to 200 kHz
o Input adaptation to current or voltage signals
o Adjustable signal conditioning for offset, amplitude and phase
o Input signal stabilization by LED or MR bridge supply tracking
(via controlled 50 mA and 2 x 10 mA highside sources)
o 2 or 3 track nonius calculation of up to 25 bit singleturn position
o Data update within 7 µs supported by flash period counting
o Serial 2-wire interface to multiturn sensors (BiSS, SSI, 2-bit)
o Fast, serial I/O interface with fail-safe RS422 transceiver
(SSI to 4 MHz, BiSS C to 10 MHz)
o Differential 1 Vpp sin/cos outputs to 100 Ω, short-circuit-proof
o Position preset function, selectable up/down code direction
o Signal and system monitoring with configurable error/warning
messaging and diagnosis memory
o Device setup via I/O interface (BiSS) or serial EEPROM
o Reverse-polarity-proof and tolerant against faulty output wiring
o Power-good switch protecting the peripheral circuitry
o Single 5 V supply, operation from -40 to +95 (+110) °C
