LTC1608ACG#PBF

Analog To Digital Converters (ADC) Overview

The LTC1608ACG#PBF is a high-speed, 16-bit sampling analog-to-digital converter (ADC) operating at 500ksps. It features a differential input sample-and-hold with a –2.5V full-scale range and accepts single-ended or differential signals up to a 15MHz bandwidth. The device utilizes a successive approximation register (SAR) architecture with no pipeline delay. Key performance metrics include 90dB S/(N+D), –100dB THD, and 68dB common mode rejection. It operates on ±5V supplies, dissipating 270mW typically, and includes two digitally selectable power shutdown modes: Nap (7mW) and Sleep (10mW).
