Overview
The LTC2170CUKG-12#TRPBF, produced by Analog Devices Inc., is a 12-bit, low power, quad analog-to-digital converter (ADC) designed for high-frequency, wide dynamic range signal digitization. This component is part of the LTC2170-12 series, which includes 12-bit, 25Msps, 40Msps, and 65Msps versions. It is particularly suited for demanding communications applications due to its excellent AC performance, including a signal-to-noise ratio (SNR) of 71dB and a spurious free dynamic range (SFDR) of 90dB. The ADC features ultralow jitter of 0.15ps RMS, enabling undersampling of IF frequencies with superior noise performance.
