Key Features
- 4 simultaneous 14-bit ADC channels each sampling at 65 Msps enabling coherent multi-channel RF and IF signal acquisition
- Low power architecture consuming under 300 mW total for all 4 channels, reducing thermal management complexity in dense PCB designs
- 2 V differential input range with 0.0198% maximum linearity error providing high dynamic range for communications and instrumentation applications
- 52-lead QFN package integrating quad ADC cores in a compact footprint suitable for multi-channel radar and software-defined radio boards
Applications
The LTC2172IUKG-14#PBF is designed for multi-channel communications receivers, software-defined radio front-ends, and medical ultrasound imaging systems that require simultaneous digitization of 4 independent IF or baseband channels at 65 Msps. Its low power consumption and 14-bit resolution make it well-suited for portable test instruments and phased-array antenna platforms where per-channel power budgets are tight. The device is also used in radar signal processors and multi-axis vibration analyzers where phase coherence across all 4 channels is essential for accurate angle-of-arrival or frequency estimation.

Frequently Asked Questions
What is the per-channel sampling rate and resolution of LTC2172IUKG-14#PBF, and how does it fit an IF digitization stage?
Each of the 4 channels samples at 65 Msps with 14-bit resolution, giving a Nyquist bandwidth of 32.5 MHz per channel that comfortably digitizes IF signals in the 10 MHz to 30 MHz range commonly used in narrowband and wideband communications receivers. The 14-bit resolution provides a theoretical 86 dB dynamic range, which is adequate for most 4G/5G sub-6 GHz and ISM-band receiver chains.
How much total power does LTC2172IUKG-14#PBF consume across all 4 channels, and how does that affect thermal design?
All 4 ADC channels operating simultaneously consume approximately 300 mW from a 1.8 V core supply, which equates to 75 mW per channel — significantly lower than discrete quad-ADC implementations that can exceed 600 mW total. The 52-lead QFN package has a thermal resistance below 30 K/W, so at 300 mW dissipation the die temperature rises only 9 degrees C above the PCB copper temperature, requiring no forced-air cooling in most rack-mount or benchtop instrument enclosures.
Can LTC2172IUKG-14#PBF replace a two-chip dual-ADC solution in a 4-channel oscilloscope front-end?
Yes, a single LTC2172IUKG-14#PBF integrates 4 simultaneous 14-bit channels at 65 Msps, replacing two separate dual-ADC ICs and cutting the component count by at least 50% while improving channel-to-channel skew to under 100 ps because all converters share one master clock and reference. This consolidation also reduces PCB routing complexity and eliminates the inter-chip clock synchronisation circuitry required in a two-chip approach.
What input voltage range does LTC2172IUKG-14#PBF accept, and does it require an external ADC driver amplifier?
The device accepts a differential input signal of plus or minus 2 V peak, corresponding to a 4 V peak-to-peak full-scale range centred at 0 V. Most RF and IF signal chains driving this input will need a low-noise differential amplifier such as the ADA4930 to convert single-ended signals to differential and provide the 2 V swing, because the input is optimised for differential drive to maintain the 14-bit linearity specification of 0.0198% maximum error.
