ADC1415S125HN-C1

Analog To Digital Converters (ADC) Overview

The ADC1415S125HN-C1 is a single-channel, 14-bit pipelined Analog-to-Digital Converter (ADC) manufactured by Renesas Electronics Corporation. It operates at a maximum sampling rate of 125 Msps and features an integrated input buffer to maintain constant low input impedance across a wide frequency range up to 600 MHz. The device supports flexible analog supply voltages of 3 V and 5 V, with digital outputs available in CMOS or Low Voltage Differential Signaling (LVDS) Double Data Rate (DDR) formats. An integrated Serial Peripheral Interface (SPI) allows for configuration of output data standards, formats, and programmable full-scale input ranges from 1 V to 2 V peak-to-peak.

Analog To Digital Converters (ADC) Feature Summary

• 14-bit resolution with a pipelined architecture ensuring zero missing codes over the operating range.
• Integrated input buffer providing 600 MHz bandwidth and isolating kickback effects from the S/H stage.
• Flexible digital output interface supporting both CMOS and LVDS DDR standards via SPI or pin control.
• Programmable full-scale input voltage range configurable between 1 V (p-p) and 2 V (p-p).

Analog To Digital Converters (ADC) Applications

• Wireless and wired broadband communications
• Ultrasound equipment and imaging systems
• Software defined radio and spectral analysis
• Digital predistortion loops for power amplifier linearization

Analog To Digital Converters (ADC) Procurement Notes

Verify component authenticity through authorized distributors as the part may be subject to obsolescence notices. Confirm package integrity upon receipt, as the HVQFN40 thermal enhanced package requires specific handling during soldering. Ensure that ordering suffixes match the required sample rate variant, as the 'C1' designation corresponds specifically to the 125 Msps speed grade within the series.

Analog To Digital Converters (ADC) Selection Notes

Select this model when high dynamic performance at 125 Msps is required alongside low power consumption. The integrated input buffer simplifies driving requirements for high-frequency signals compared to buffered alternatives. Consider the separate digital supply voltage (VDDO) capability, which allows compatibility with 1.8 V to 3.3 V logic levels regardless of the analog supply. Verify that the 6-layer board recommendation is met to achieve the specified thermal resistance characteristics.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADC1415S series, which includes variants with different maximum sampling rates: 65 Msps, 80 Msps, 105 Msps, and 125 Msps. All members of the series share identical pinouts and functional blocks, differing primarily in their clock frequency limits and associated dynamic performance metrics. The series is designed to be pin-compatible with the ADC1215S, ADC1015S, and ADC1115S125 families.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include the ADC1415S065HN-C1, ADC1415S080HN-C1, and ADC1415S105HN-C1. These parts offer lower maximum sampling rates but retain the same package and functionality. Cross-series compatibility exists with ADC1215S, ADC1015S, and ADC1115S125 devices.
