AN121E04

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

The AN121E04 and all 5volt (Vortex Family) FPAA's are now at the end of life.

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

The AN121E04 Statically Reconfigurable Field Programmable Analog Array with Rich I/O Cell Design

This device features an advanced input/output structure that allows the FPAA to be programmed with up to six outputs – or triple the number provided by the ANx20E04 devices. The ANx21E04 devices have four configurable I/O cells and two dedicated output cells. For I/O-intensive applications, this means a single FPAA can now be used to process multiple channels of analog signals where two or more such devices were previously needed.

The AN121E04 device provides a low-cost path to implementing analog signal conditioning in high-volume applications.

Features:

· 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 (10x10x2mm)

o Lead pitch 0.8mm

· Supply voltage: 5V
