Product description

iC-NV is a sine/cosine-to-digital converter using a flash principle for speedy conversion.

A pin-configured minimum edge distance control is its unique feature to guarantee glitch-free encoder quadrature output signals including a gated index signal (AB-gated, or A-gated for iC-NVH).

Features

  • Fast flash converter
  • Integrated glitch filter; minimum transition distance can be set using the optional resistor
  • Selectable resolution of up to 64 steps per cycle and up to 16-fold interpolation
  • Integrated instrumentation amplifiers with adjustable gain
  • Direct connection of sensor bridges, no external components required
  • 200 kHz input frequency with the highest resolution
  • Incremental A QUAD B output of up to 3.2 MHz
  • Reversed A/B phase selectable
  • Index signal processing
  • Sensor bridge calibration supportable by analog/digital test signals
  • Low power consumption from single 5 V supply
  • TTL- /CMOS-compatible outputs
  • Inputs and outputs protected against destruction by ESD

Applications

  • Angle interpolation from orthogonal sinusoidal input signals
  • Linear and rotary encoders
  • MR sensor systems
