Product description

The general purpose sensor signal conditioner iC-TW3 provides
highly accurate non contact trimming of three independent sine/cosine sensor signals.

An automatic gain and offset control compensates sensor signal errors and stabilizes the differential output signals at 1 Vpp or 2 Vpp.

The internal or an external temperature sensor linked to the chip can influence the gain and offset correction by arbitrary temperature-dependent compensation parameters sourced from a look-up table.

Features

  • Fully differential 3-channel signal conditioning
  • PGS inputs for differential and single-ended signals
  • Overall gain of -3 to 57 dB, adjustable in steps of 0.08 dB
  • Output referred offset range of ± 1.2 V, adjustable in steps of 2 mV
  • Signal bandwidth to 1 MHz and in/out latency below 1 µs
  • Selectable automatic gain and offset control for encoder applications
  • On-chip or off-chip temperature sensing
  • Temperature drift compensation for gain and offset via programmable look-up tables
  • Short-circuit-proof outputs: 1 Vpp to 100 Ω, 2 Vpp to 1 kΩ
  • I2C interface to restore device setup from serial EEPROM
  • Bidirectional 1-wire interface for direct RAM and EEPROM access
  • Optical setup link via 1-wire interface operating a photo receiver
  • Single 3.0 V to 5.5 V supply
  • Operating temperature range of –40 to +125 °C

Applications

  • Programmable general purpose sensor interface
  • Optical position sensors
  • Magnetic position sensors
  • Incremental position sensors
  • Linear scales
