The AN231E04 is Okika’s flagship FlexAnalog™ field-programmable analog array (FPAA), featuring four Configurable Analog Blocks (CABs) and seven analog I/Os that support both differential and single-ended signals. Each CAB can be configured to implement up to 50 proven analog functions using verified Configurable Analog Modules (CAMs).
AN234E04 Integrated Circuit Block Diagram
Designed for versatility, the AN231E04 excels in signal conditioning, filtering, gain control, rectification, summing, subtraction, multiplication, and more. An integrated 8x256-bit look-up table supports complex nonlinear operations such as sensor response linearization and arbitrary waveform generation.
With a unity gain bandwidth of 18 MHz and the ability to process signals up to 2 MHz, it’s well-suited for applications like audio and sonar processing, IF filtering, and high-frequency systems such as RFID readers. Its dynamic, software-controlled reprogramming capability allows real-time adjustments—enabling adaptive filtering, self-calibration, aging compensation, dynamic range compression, and other advanced analog-software optimization techniques.
Design Library & Automated Design Functions
The AN231E04 FPAA integrated circuit has access to a deep design library of analog components, plus the ability to easily configure low level blocks or higher level analog functions (such as filters, multipliers, etc). Through the AnadigmDesigner2 EDA software, the analog components and configurable functions are available.
