AN221E04

----------NOT RECOMMENDED FOR NEW DESIGN----------

The AN221E04 and all 5volt (Vortex Family) FPAA's are now at the end of life.

For new designs please use the AN231E04 FPAA (dpASP).

AN221E04 device provides a significantly improved signal-to-noise ratio as well as higher bandwidth. These devices also accommodate nonlinear functions such as sensor response linearization and arbitrary waveform synthesis.

With dynamic reconfigurability, the functionality of the AN221E04 can be reconfigured in-system by the designer or on-the-fly by a microprocessor. A single AN221E04 can thus be programmed to implement multiple analog functions and/or to adapt on-the-fly to maintain precision operation despite system degradation and aging.

FEATURES:

· Dynamic reconfiguration

· Four configurable I/O cells, two dedicated output cells

· 8-bit SAR analog–to–digital converter

· Fully differential architecture

· Fully differential I/O buffering with options for single ended to differential conversion

· Low input offset through chopper stabilized amplifiers

· 256 Byte Look-Up Table (LUT) for linearization and arbitrary signal generation

· 4:1 Input multiplexer

· Typical Signal Bandwidth: DC-2MHz (Bandwidth is CAM dependent)

· Signal to Noise Ratio:

o Broadband 80dB

o Narrowband (audio) 100dB

· Total Harmonic Distortion (THD): 80dB

· DC offset <100µV

· Package: 44-pin QFP (10x10x1.4mm)

o Lead pitch 0.8mm

· Supply voltage: 5V
