ADC1412D125HN/C1:5

Analog To Digital Converters (ADC) Overview

The ADC1412D125HN/C1:5 is a dual-channel, 14-bit pipelined Analog-to-Digital Converter (ADC) from NXP Semiconductors. It supports sampling rates up to 125 Msps with an input bandwidth of 600 MHz. The device operates on a single 3 V analog supply and features flexible digital output options in CMOS or LVDS DDR formats. Key performance metrics include a typical Signal-to-Noise Ratio (SNR) of 71.4 dBFS and Spurious-Free Dynamic Range (SFDR) of 87 dBc at 125 Msps. It incorporates an integrated SPI for configuration, programmable full-scale input ranges, and duty cycle stabilization.

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix ':5' against the manufacturer's current documentation to confirm specific packaging details such as reel size or tape-and-reel specifications. Confirm that the HVQFN64 package variant matches the thermal requirements of the target PCB layout. Ensure compatibility with existing design files if replacing older revisions of the ADC1412D series.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high dynamic performance is required at sample rates up to 125 Msps. Choose the LVDS DDR output mode for noise-immune applications requiring higher data throughput, or CMOS mode for simpler interface designs. Verify that the system clock jitter is minimized, as the device includes a clock input divided by 2 to reduce jitter contribution. Ensure the analog input common-mode voltage is set to approximately 0.5VDDA for optimal performance.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC1412D series, which includes variants with different maximum sampling rates: ADC1412D065 (65 Msps), ADC1412D080 (80 Msps), and ADC1412D105 (105 Msps). All variants share the same HVQFN64 package and pinout, offering pin and software compatibility within the series. The device is designed to be compatible with the earlier ADC1212D and ADC1112D125 series.

Analog To Digital Converters (ADC) Replacement Considerations

For direct pin-compatible replacements within the same family, consider the ADC1412D065HN/C1, ADC1412D080HN/C1, or ADC1412D105HN/C1. These parts offer lower sampling rates but maintain identical functionality and package dimensions.
