ADS6422IRGCR

Analog To Digital Converters (ADC) Overview

The ADS6422IRGCR is a quad-channel, 12-bit analog-to-digital converter (ADC) from Texas Instruments. It operates at a sampling rate of 65 MSPS with a pipeline architecture. The device features differential inputs and LVDS outputs. It requires a 3.3 V analog supply and a 3 V to 3.6 V digital supply. Key performance metrics include a signal-to-noise ratio (SNR) of 71 dB, an effective number of bits (ENOB) of 11.5 bits, and a full power bandwidth supporting high-frequency applications. Differential nonlinearity (DNL) is +/- 1.8 LSB, while integral nonlinearity (INL) is +/- 2 LSB. Power consumption is typically 1.05 W, with a maximum dissipation of 1.25 W. It is housed in a VQFN-64 package and functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates four independent 12-bit ADC channels for simultaneous multi-channel data acquisition.
• Supports high-speed digitization with a 65 MSPS sampling rate per channel.
• Includes an I2C interface for configuration and control settings.
• Delivers high linearity performance with specified DNL and INL limits.

Analog To Digital Converters (ADC) Applications

• Software-defined radio systems
• Wireless infrastructure base stations
• Test and measurement instrumentation

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'RGCR' corresponds to the reel packaging format when ordering. Confirm that the required development kit, such as the ADS6422EVM, is available for evaluation purposes. Ensure compliance with RoHS standards and moisture sensitivity levels during storage and handling procedures prior to assembly.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a quad-channel solution is required for 12-bit resolution at moderate speeds. Compare against the ADS6425 series if higher sampling rates like 125 MSPS are needed. Consider the ADS5263 for applications requiring 16-bit resolution. Verify that the LVDS output interface matches the downstream FPGA or processor requirements.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS6422 family of high-performance quadruple ADCs. It shares the VQFN-64 package form factor with other Texas Instruments data converters like the ADS62P19 and ADS5263. The 'IRGCR' designation indicates the industrial temperature range, tape and reel packaging, and specific pinout configuration defined by the manufacturer.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS6425IRGCT is a faster variant within the same family offering 125 MSPS. Check datasheet compatibility for pinouts and register maps before substitution. No direct cross-model substitutes are confirmed in public documentation without functional verification.
