Overview
The LTC2142IUP-14#TRPBF is a high-performance, 14-bit, dual-channel, simultaneously sampling analog-to-digital converter (ADC) produced by Analog Devices Inc. This component is designed to digitize high-frequency, wide dynamic range signals, making it ideal for demanding applications in communications, medical imaging, and data acquisition.
With its advanced features and low power consumption, the LTC2142IUP-14#TRPBF offers excellent AC performance, including a signal-to-noise ratio (SNR) of 73.2dB and a spurious free dynamic range (SFDR) of 90dB. The ultralow jitter of 0.08ps RMS enables undersampling of IF frequencies with superior noise performance.
