LTC1409IG

Analog To Digital Converters (ADC) Overview

The LTC1409IG is a 12-bit, 800ksps sampling analog-to-digital converter (ADC) manufactured by Linear Technology. It integrates a high-speed successive approximation register architecture with a built-in track-and-hold amplifier and a precision voltage reference. The device operates from a single 5V supply and features a shutdown mode to minimize power consumption during idle periods. Designed for applications requiring moderate resolution and speed, it utilizes a serial interface compatible with standard microprocessor protocols. The component is housed in a 16-lead SSOP package, suitable for space-constrained designs.
