ADC08D1520CIYB

Analog To Digital Converters (ADC) Overview

The ADC08D1520CIYB is a dual, low-power, high-performance CMOS analog-to-digital converter from Texas Instruments. It provides 8-bit resolution at sample rates up to 1.5 GSPS per channel. The device supports interleaved operation for a combined 3.0 GSPS rate and features selectable output demultiplexing (1:1 or 1:2). It operates on a single +1.9V supply, consuming approximately 1.6W in non-demux mode at 1.0 GSPS. Key specifications include a typical ENOB of 7.4 bits at 748 MHz input, a code error rate of 10^-18, and LVDS digital outputs compatible with IEEE 1596.3-1996 standards.

Analog To Digital Converters (ADC) Feature Summary

Analog To Digital Converters (ADC) Applications

• Direct RF Down Conversion systems
• Digital Oscilloscopes
• Satellite Set-top boxes
• Communications Systems
• Test Instrumentation

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current product folder to confirm package type and environmental compliance. Ensure that the HLQFP package thermal pad is properly soldered to a ground plane during assembly to maintain rated performance and thermal resistance specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high-speed sampling above 1 GSPS is required with moderate 8-bit resolution. Consider the 1:2 demux mode if downstream logic requires lower data rates than the full sample clock. Verify that the system can accommodate the 1.9V supply requirement and provide adequate bypassing for both VA and VDR pins to achieve specified dynamic performance.

Analog To Digital Converters (ADC) Part Context

The ADC08D1520 builds upon the ADC08D1500 platform, offering expanded features such as test pattern output for system debug, adjustable input full-scale range, and clock phase adjustment. It utilizes a unique folding and interpolating architecture with fully differential comparators to achieve high dynamic performance beyond Nyquist frequencies.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC08D1500 is a related predecessor model. When evaluating replacements, verify compatibility with the 128-pin HLQFP package and ensure that the target device supports the required 1.5 GSPS interleaved operation and LVDS output interface.
