ADC1415S105HN/C1,5

Analog To Digital Converters (ADC) Overview

The ADC1415S105HN/C1,5 is a single-channel 14-bit analog-to-digital converter (ADC) from NXP Semiconductors. It operates at a maximum sampling rate of 105 Msps and features a pipelined architecture with output error correction to ensure zero missing codes. The device includes an integrated input buffer that maintains constant low input impedance across a wide frequency range, supporting an input bandwidth of 600 MHz. It accepts differential or single-ended analog inputs with a programmable full-scale voltage range of 1 V to 2 V peak-to-peak. Digital outputs are available in CMOS or Low Voltage Differential Signaling (LVDS) Double Data Rate (DDR) formats.

• Spectral analysis and portable instrumentation

Analog To Digital Converters (ADC) Procurement Notes

Verify the complete part number including the ordering suffix ',5' which indicates tape and reel packaging. Confirm the HVQFN40 package variant SOT618-6 matches the design requirements. Ensure the specific speed grade corresponds to the 105 Msps requirement rather than other variants in the series such as 65, 80, or 125 Msps.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high dynamic performance at intermediate frequencies. The integrated input buffer simplifies driving requirements by isolating the sample-and-hold kickback effect. Verify power supply constraints, as the device requires separate 3 V and 5 V analog supplies and a 1.8 V to 3.3 V digital supply. Consider thermal dissipation characteristics when designing the PCB layout.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC1415S series, which includes variants operating at 65, 80, 105, and 125 Msps. All members share pin compatibility and architectural similarities, differing primarily in maximum sampling rates. The series is designed for low power consumption while maintaining high accuracy with integral non-linearity of ±5 LSB and differential non-linearity of ±0.95 LSB.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives within the same family include the ADC1415S065, ADC1415S080, and ADC1415S125. These parts share the same package and pinout but offer different maximum sampling speeds. Cross-referencing with the ADC1215S or ADC1015S series may be possible if lower resolution is acceptable.
