LTC2153CUJ-12

Analog To Digital Converters (ADC) Overview

The LTC2153CUJ-12 is a 12-bit, 310Msps analog-to-digital converter (ADC) designed for high-frequency signal digitization. It operates on a single 1.8V supply with a total power dissipation of 378mW. The device features a 1.25GHz full-power bandwidth sample-and-hold circuit and supports undersampling applications. Key AC performance metrics include a typical Signal-to-Noise Ratio (SNR) of 67.6dBFS at 70MHz input and an Spurious Free Dynamic Range (SFDR) of 88dB. DC specifications provide ±0.6LSB Integral Nonlinearity (INL) and ±0.1LSB Differential Nonlinearity (DNL). Digital outputs are Double Data Rate (DDR) LVDS, and the component includes an optional clock duty cycle stabilizer and low power sleep/nap modes.
