AD9012TQ/883B

Overview

The AD9012TQ/883B is a high-speed 8-bit analog-to-digital converter (ADC) manufactured by Analog Devices Inc. under the MIL-PRF-38534 qualification standard. It utilizes a flash conversion architecture to achieve a maximum sampling rate of 76.9 MSPS with a typical conversion time of 13 ns. The device operates on dual supplies, typically ±5 V, and features an 8-bit parallel digital output interface. Housed in a 28-lead ceramic flatpack package, it is designed for military and aerospace environments requiring radiation hardness and extended temperature stability.
