ADC12D500RFIUT/NOPB

Analog To Digital Converters (ADC) Overview

The ADC12D500RFIUT/NOPB is a dual-channel, high-speed analog-to-digital converter manufactured by Texas Instruments. It features a folding interpolating architecture with 12-bit resolution and supports sampling rates up to 500 MSPS per channel in dual mode, or 1 GSPS in single mode. The device utilizes a low-latency LVDS interface for data output. Key electrical specifications include an analog supply voltage of 1.9 V and digital supply voltages ranging from 1.8 V to 2 V. Performance metrics indicate a Signal-to-Noise Ratio (SNR) of approximately 54.6 dB and an Effective Number of Bits (ENOB) of 9.6 bits. The component operates within a temperature range of -40°C to +85°C and is housed in a BGA-292 package.

• Dual-channel architecture allowing flexible configuration between two 500 MSPS channels or one 1 GSPS channel.
• Folding interpolating structure designed for ultra-high-speed RF sampling applications.
• Low-latency LVDS interface supporting deterministic timing and simplified synchronization.

Analog To Digital Converters (ADC) Applications

• Software Defined Radio (SDR)
• Electronic Warfare (EW) systems
• Wideband signal monitoring

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required packaging and environmental standards. Confirm that the BGA-292 footprint matches the target PCB design constraints. Check for any export control restrictions associated with high-performance data converters originating from the designated manufacturer.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel input acquisition at 500 MSPS or single-channel operation at 1 GSPS is required. Ensure the system design accommodates the specific 1.9 V analog and 1.8–2 V digital power rails. Evaluate the LVDS interface requirements against the downstream processing unit's capabilities to guarantee signal integrity at high speeds.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC12D1000RF family of RF sampling ADCs from Texas Instruments. It shares architectural similarities with higher-speed variants like the ADC12D1000 but offers optimized performance for 500 MSPS dual-channel applications. The series is characterized by its folding interpolating topology and low-latency digital outputs suitable for direct RF sampling.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes within the same family include the ADC12D1000RFIUT/NOPB for higher speed requirements, provided the pinout and interface remain compatible. Cross-family replacements require careful evaluation of latency, interface type, and power consumption differences.
