LTC2323HUFD-12#PBF

Analog To Digital Converters (ADC) Overview

The LTC2323HUFD-12#PBF is a dual-channel, 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices. It operates at a sampling rate of 5Msps with differential or pseudo-differential input configurations. The device features an internal reference and supports single-ended inputs. Key electrical specifications include a maximum power dissipation of 55mW, a differential nonlinearity (DNL) of 0.4 LSB, and an integral nonlinearity (INL) of 1 LSB. It provides an 88 dB spurious-free dynamic range (SFDR) and a signal-to-noise and distortion ratio (SINAD) of 79 dB. The component is housed in a 28-lead QFN package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the manufacturer part number against official Analog Devices documentation to ensure authenticity. Confirm that the HUFD suffix corresponds to the specified temperature range and package variant. Check RoHS compliance status through the manufacturer's current product specification sheet before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel conversion is required within a compact footprint. Ensure the system clock frequency matches the 5Msps requirement. Verify that the input voltage range aligns with the differential or pseudo-differential input capabilities. Consider the 55mW power budget if thermal management is constrained in the application design.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2323 family of high-speed SAR ADCs. It shares architectural similarities with the LTC2311 (single channel) and LTC2325 (quad/octal channels). The 12-bit resolution variant offers a balance between speed and precision compared to the 14-bit and 16-bit versions in the same series.

Analog To Digital Converters (ADC) Replacement Considerations

The LTC2311 serves as a single-channel alternative within the same family. For quad-channel requirements, the LTC2325 is the corresponding option. Cross-referencing should be limited to parts explicitly listed in the manufacturer's compatibility documentation.
