LTC2175IUKG-14 | ADI ADC | 14-bit quad ADC | 125Msps Converter
The LTC2175IUKG-14 is a 14-bit, 125Msps, 4-channel simultaneous sampling ADC from Analog Devices (formerly Linear Technology), engineered for digitizing high-frequency, wide dynamic range signals in demanding communication and instrumentation systems. This low-power quad ADC delivers 73.1dB SNR and 88dB spurious-free dynamic range (SFDR) with ultralow 0.15ps RMS jitter enabling undersampling of IF frequencies with excellent noise performance.
The device operates from a single 1.8V supply, consuming just 558mW total (140mW per channel), and features serial LVDS outputs in 1-lane or 2-lane modes with optional internal termination and adjustable output levels. DC specifications include ±1LSB INL (typ), ±0.3LSB DNL (typ), and no missing codes over temperature with 1.2LSB RMS transition noise. Packaged in a 52-QFN with industrial-grade -40°C to +85°C operation, the LTC2175IUKG-14 targets cellular base stations, software-defined radios, portable medical imaging, and multichannel data acquisition systems.

Applications
● Communications infrastructure and wireless transceiver systems requiring multichannel high-speed digitization.
● Cellular base stations with I/Q receiver architectures benefiting from simultaneous sampling.
● Software-defined radios (SDR) demanding wide dynamic range and low jitter performance.
● Portable medical imaging equipment including ultrasound and portable diagnostics.
● Multichannel data acquisition systems for industrial test and measurement.
● Nondestructive testing (NDT) instrumentation requiring precise multi-channel signal capture.
FAQs
Q: What is the difference between LTC2175-14, LTC2174-14, and LTC2173-14? A: The three versions differ only in sampling rate - LTC2175-14 operates at 125Msps, LTC2174-14 at 105Msps, and LTC2173-14 at 80Msps - sharing identical pinouts, packages, and features.
Q: How much power does the device consume in sleep mode? A: Sleep mode powers down the entire chip to just 1mW, with recovery time dependent on VREF, REFH, and REFL bypass capacitor values (typically 2ms with recommended components).
Q: What digital output formats are supported? A: Serial LVDS outputs with selectable 1-lane (one bit per channel) or 2-lane (two bits per channel) modes, plus 2's complement or offset binary output formatting and digital output randomization options.
