LTC1412CG#PBF

Analog To Digital Converters (ADC) Overview

The LTC1412CG#PBF is a 12-bit, 3Msps sampling analog-to-digital converter (ADC) from Analog Devices. It integrates a high dynamic range sample-and-hold circuit and a precision internal reference. Operating from ±5V supplies, the device dissipates 150mW. The ADC features true differential inputs with a –2.5V bipolar input range optimized for low noise and distortion. Key performance metrics include 72dB S/(N + D) and 82dB SFDR at the Nyquist frequency of 1.5MHz. It utilizes a successive approximation architecture with no pipeline delay, providing direct parallel output compatible with 3V logic via the OVDD pin.
