LTC1409CSW#PBF

Analog To Digital Converters (ADC) Overview

The LTC1409CSW#PBF is a 12-bit, 800ksps sampling A/D converter featuring a high dynamic range sample-and-hold and a precision internal reference. It operates from ±5V supplies with a power dissipation of 80mW. The device accepts true differential inputs within a ±2.5V range, providing 60dB common mode rejection. Key performance metrics include 72.5dB S/(N + D) at the Nyquist frequency of 400kHz and no pipeline delay. It offers two digitally selectable shutdown modes: Nap (4mW) and Sleep (10μW). The part is housed in a 28-lead SO Wide package.
