LTC2150CUJ-12#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC2150CUJ-12#TRPBF is a single-channel, 12-bit analog-to-digital converter (ADC) operating at a sampling rate of 170 Msps. It features a 1.25 GHz full-power bandwidth sample-and-hold circuit and accepts a 1.5 V peak-to-peak differential input signal. The device utilizes double-data rate (DDR) LVDS digital outputs and operates on a single 1.8 V supply with typical power dissipation of 306 mW. Key performance metrics include a signal-to-noise ratio (SNR) of 68.5 dBFS and a spurious-free dynamic range (SFDR) of 90 dBFS at 70 MHz input frequency. Integral nonlinearity is typically ±0.30 LSB, and differential nonlinearity is typically ±0.16 LSB.

Analog To Digital Converters (ADC) Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging for automated assembly. Confirm the CUJ designation corresponds to the commercial temperature range of 0°C to 70°C. Ensure the QFN package dimensions match the PCB footprint requirements. Check for RoHS compliance documentation as specified in the manufacturer's ordering information.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 170 Msps sampling rate is sufficient for the application, offering lower power consumption compared to the 250 Msps LTC2152-12 variant. The internal reference simplifies design by reducing external component count. Verify that the 1.5 Vpp input range aligns with the source signal amplitude. Consider the 40-lead QFN package size for board space constraints.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC215x-12 family of high-speed ADCs from Analog Devices. It shares pin compatibility and architectural similarities with the LTC2151-12 (210 Msps) and LTC2152-12 (250 Msps). The primary distinction is the maximum sampling frequency, which dictates the specific power and bandwidth characteristics of the LTC2150-12 model.

Analog To Digital Converters (ADC) Replacement Considerations

LTC2151CUJ-12#TRPBF offers higher speed (210 Msps) with similar power profiles. LTC2152CUJ-12#TRPBF provides 250 Msps operation. For lower speed requirements, the LTC2257-12 series may be considered for ultra-low power applications.
