ADC1610S125HN-C1

Analog To Digital Converters (ADC) Overview

The ADC1610S125HN-C1 is a single-channel, 16-bit pipelined Analog-to-Digital Converter (ADC) designed for high dynamic performance and low power consumption at sample rates up to 125 Msps. It operates from a single 3 V analog supply (2.85 V to 3.4 V) and supports separate digital output supplies of 1.8 V to 3.6 V in CMOS mode or 2.85 V to 3.6 V in LVDS DDR mode. The device features an integrated Serial Peripheral Interface (SPI) for configuration, including programmable full-scale input ranges from 1 V to 2 V peak-to-peak. It guarantees zero missing codes across the operating range and offers flexible data formats such as offset binary, two's complement, and gray code.

Analog To Digital Converters (ADC) Procurement Notes

Verify the component status as the datasheet indicates potential obsolescence or lifecycle changes associated with the IDT acquisition by Renesas. Confirm the specific ordering suffix matches the required package variant and thermal characteristics. Ensure compatibility with the HVQFN40 footprint dimensions (6 x 6 x 0.85 mm) during PCB layout planning.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a 16-bit resolution and 125 Msps throughput are required. Consider the ADC1610S105HN-C1, ADC1610S080HN-C1, or ADC1610S065HN-C1 if lower sampling rates suffice, as they offer reduced power dissipation. Evaluate the need for LVDS DDR outputs versus CMOS based on board trace length and noise immunity requirements.

Analog To Digital Converters (ADC) Part Context

The ADC1610S series includes variants with different maximum sampling rates: 65 Msps, 80 Msps, 105 Msps, and 125 Msps. All variants share the same HVQFN40 package and pinout but differ in clock frequency limits and power consumption profiles. The ADC1610S125HN-C1 represents the highest speed option within this specific family.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same series include ADC1610S105HN-C1, ADC1610S080HN-C1, and ADC1610S065HN-C1. These alternatives provide identical packaging and functionality but operate at lower maximum sampling frequencies.

Analog To Digital Converters (ADC) FAQ

What is the typical power dissipation at 80 Msps?

The power dissipation is typically 430 mW when operating at an 80 Msps sample rate with only the analog supply considered.

How is the full-scale input voltage configured?

The full-scale input voltage is programmable between 1 V (p-p) and 2 V (p-p) via the internal reference settings controlled through the SPI interface or specific pin configurations.

What data formats does the ADC support?

The device supports offset binary, two's complement, and gray code output data formats, which can be selected via the SPI interface or the DFS pin.
