AD2S1200 - 12-Bit R/D Converter with Reference Oscillator

General Description

The AD2S1200 is a complete 12-bit resolution tracking resolverto-digital converter, integrating an on-board programmable sinusoidal oscillator that provides sine wave excitation for resolvers.

An external 8.192 MHz crystal is required to provide a precision time reference.

Key Features

  • Complete monolithic R/D converter Parallel and serial 12-bit data ports System fault detection Absolute position and velocity outputs Differential inputs ±11 arc minutes of accuracy 1,000 rps maximum tracking rate, 12-bit resolution Incremental encoder emulation (1,024 pulses/rev) Programmable sinusoidal oscillator on-board Compatible with DSP and SPI® interface standards 204.8 kHz square wave output Single-supply operation (5.00 V ± 5%).
  • 40°C to +125°C temperature rating 44-lead LQFP pa.
