DESCRIPTION
The general purpose sensor signal conditioner iCTW3 provides highly accurate non contact trimming of three independent sine/cosine sensor signals. The differential output signals can be calibrated to 1 Vpp or to 2 Vpp, alternatively.

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
