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