LTC2175IUKG-12

Analog To Digital Converters (ADC) Overview

The LTC2175IUKG-12 is a 4-channel, simultaneous sampling 12-bit analog-to-digital converter (ADC) from Analog Devices. It operates at a maximum sampling rate of 125Msps with a pipeline architecture and serial LVDS outputs. The device features an internal reference, supports differential or single-ended inputs, and includes shutdown and nap modes for power management. Key electrical specifications include a typical Signal-to-Noise Ratio (SNR) of 70.6dB, Spurious Free Dynamic Range (SFDR) of 88dB, Integral Nonlinearity (INL) of ±0.3LSB, and Differential Nonlinearity (DNL) of 0.1LSB. Total power dissipation is 136mW.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix '#PBF' indicates lead-free packaging compliant with RoHS standards. Confirm the 'I' grade designation matches the required operating temperature range of -40°C to +85°C. Ensure the QFN-52 package dimensions align with the PCB footprint design.

Analog To Digital Converters (ADC) Selection Notes

Select this component when four synchronized channels are required at high speeds. Compare against the LTC2175-14 series if higher resolution is needed, noting the trade-off in power consumption. Verify that the serial LVDS interface is compatible with the downstream FPGA or processor logic levels.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2175 family of low-power quad ADCs. It shares pin compatibility with the 14-bit variants (LTC2175-14), allowing for design flexibility across different resolution requirements within the same package form factor.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives within the same family include the LTC2175CUKG-12#PBF for commercial temperature ranges and the LTC2175-14 variants for increased resolution.
