AD7828TE/883B

Overview

The AD7828TE/883B is a high-speed, 12-bit analog-to-digital converter (ADC) designed for military and aerospace applications. It features four analog input channels with integrated track-and-hold circuits, enabling a sampling rate of up to 4 MSPS per channel. The device operates on a single 5V supply and utilizes a parallel interface for fast microprocessor communication. It includes an internal reference voltage and supports a wide operating temperature range from -55°C to +125°C.

Feature Summary

• Four independent analog input channels with built-in track-and-hold functionality
• High-speed parallel digital interface for rapid data transfer
• Internal precision voltage reference eliminates external component requirements
• Radiation-hardened design suitable for harsh environmental conditions

Applications

• Military radar signal processing systems
