ADC1412D105HN-C1

Analog To Digital Converters (ADC) Overview

The ADC1412D105HN-C1 is a dual-channel, 14-bit Analog-to-Digital Converter (ADC) from the Renesas/IDT ADC1412D series, operating at a maximum sample rate of 105 Msps. It utilizes a pipelined architecture with output error correction to ensure zero missing codes across its operating range. The device supports flexible input voltage ranges from 1 V to 2 V peak-to-peak and offers both CMOS and Low Voltage Differential Signaling (LVDS) Double Data Rate (DDR) digital outputs. Powered by a single 3 V analog supply and a separate digital output supply, it features an integrated Serial Peripheral Interface (SPI) for configuration. Key dynamic performance metrics include a Signal-to-Noise Ratio (SNR) of approximately 71.8 dBFS and a Spurious-Free Dynamic Range (SFDR) of 85 dBc.

Analog To Digital Converters (ADC) Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific ordering suffix matches the required package variant and thermal characteristics. Check for obsolescence status as IDT products may have transitioned to Renesas Electronics Corporation. Ensure compatibility with existing system power supplies and clocking infrastructure before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a dual-channel 14-bit resolution is required at speeds up to 105 Msps. Choose between CMOS and LVDS DDR outputs based on board trace length and noise immunity requirements. Ensure the design accommodates the separate analog (VDDA) and digital (VDDO) supply rails. Verify that the input signal bandwidth and common-mode voltage levels align with the device's 600 MHz input bandwidth and 0.9 V to 2 V common-mode range specifications.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADC1412D family, which includes variants with different maximum sampling rates such as the ADC1412D065 (65 Msps), ADC1412D080 (80 Msps), and ADC1412D125 (125 Msps). All members share pinout compatibility and similar architectural features, allowing for design flexibility across different speed requirements within the same product line.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives within the same family include the ADC1412D065HN-C1, ADC1412D080HN-C1, and ADC1412D125HN-C1. These parts offer identical packaging and functionality but differ in maximum sampling frequency. Ensure the selected replacement meets or exceeds the required 105 Msps throughput if speed is critical.
