1.1 Introduction

The DAC90802EVM is a dual‐channel, 18-bit, voltage output, digital‐to‐analog converter (DAC) utilizing a proprietary multiplying DAC (MDAC) architecture, capable of ±23.5V supply span operation. A dynamic signal range of ±21V is supported for the reference inputs, and voltage feedback at the RFBx pin, where gain options of 1, 2, and 4 are digitally selectable. 66MHz serial data interface with up to four serial data lines (SDIO0 through SDIO3) in dual data rate (DDR) mode, supports update rates up to 33MUPS in high speed 16-bit mode, and 22MUPS in high resolution 18-bit mode. Per channel edge-sensitive LDACx inputs allow fine skew control of the DAC output from previously loaded input registers. System reset is supported through the RESET pin. RESET forces the DACs to mid code in default mode.

The user guide describes the characteristics, operation, and recommended use cases of the DAC90802EVM. The user guide provides examples and instructions on how to use the DAC90802EVM board and included software. Throughout the document, the terms evaluation board, evaluation module, and EVM are synonymous with the DAC90802EVM. The user guide also includes a schematic, reference printed circuit board (PCB) layout, and a complete bill of materials (BOM).
