LTC1273ACSW#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1273ACSW#TRPBF is a 12-bit, 300ksps sampling analog-to-digital converter (ADC) utilizing successive approximation architecture. It operates on a single 5V supply and accepts unipolar analog input voltages ranging from 0V to 5V. The device integrates a precision 2.42V reference with 25ppm/°C drift, an internal synchronized clock, and a 600ns sample-and-hold circuit. Typical power dissipation is 75mW. Key performance metrics include ±1/2LSB maximum integral nonlinearity (INL), ±3/4LSB differential nonlinearity (DNL), 70dB signal-to-noise plus distortion ratio, and 77dB total harmonic distortion at the Nyquist frequency.
