ADC1412D105HN-C18

Analog To Digital Converters (ADC) Overview

The ADC1412D105HN-C18 is a dual-channel, 14-bit Analog-to-Digital Converter (ADC) from the ADC1412D series. It operates at a maximum sampling rate of 105 Msps and utilizes a pipelined architecture with output error correction to ensure zero missing codes. The device supports both CMOS and Low Voltage Differential Signaling (LVDS) Double Data Rate (DDR) digital outputs. Powered by a single 3 V analog supply (2.85 V to 3.4 V), it features an integrated Serial Peripheral Interface (SPI) for configuration and programmable full-scale input ranges from 1 V to 2 V peak-to-peak. It is housed in a 64-terminal HVQFN package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the component status as discontinued or obsolete through official Renesas channels before design finalization. Confirm that the HVQFN64 package thermal requirements are met in the target PCB layout. Ensure compatibility with existing system clocks and voltage levels given the specific operating constraints of the ADC1412D105 variant.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a 105 Msps sampling rate is required for dual-channel applications. Compare against the ADC1412D125HN-C18 if higher throughput is needed, or the ADC1412D080HN-C18 for lower power consumption. Verify that the chosen digital output interface (CMOS vs. LVDS DDR) matches the downstream processing logic requirements.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC1412D series, which includes variants with sampling rates of 65 Msps, 80 Msps, 105 Msps, and 125 Msps.
