ADC08D1500CIYB/NOPB

Analog To Digital Converters (ADC) Overview

The ADC08D1500CIYB/NOPB is a dual-channel, low-power CMOS analog-to-digital converter manufactured by Texas Instruments. It digitizes signals to an 8-bit resolution at sample rates up to 1.7 GSPS. The device operates from a single +1.9V ±0.1V supply and typically consumes 1.8 Watts at 1.5 GSPS. Key electrical specifications include a typical Effective Number of Bits (ENOB) of 7.25 bits at a 748 MHz input signal with a 1.5 GHz sample rate, and a differential non-linearity (DNL) of ±0.15 LSB. It features folding and interpolating architecture, ensuring no missing codes across the full operating temperature range.

Analog To Digital Converters (ADC) Feature Summary

• Internal self-calibration scheme enabling flat dynamic response beyond Nyquist frequency
• LVDS digital outputs compatible with IEEE 1596.3-1996 standard
• Integrated 1:2 demultiplexer to reduce output data rate on each bus

Analog To Digital Converters (ADC) Applications

• Direct RF Down Conversion
• Digital Oscilloscopes
• Satellite Set-Top Boxes
• Communications Systems
• Test Instrumentation

Analog To Digital Converters (ADC) Procurement Notes

Verify that the exposed pad on the back of the 128-lead HLQFP package is soldered to the ground plane to ensure rated thermal and electrical performance. Confirm that the ordering suffix NOPB indicates lead-free and RoHS compliance. Ensure the design accommodates the industrial temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high-speed sampling up to 1.7 GSPS with 8-bit resolution is required. It is suitable for applications needing interleaved operation as a single 3 GSPS ADC. Consider the 1.8W typical power consumption and the need for a single 1.9V supply. Verify compatibility with LVDS interfaces and check if the internal sample-and-hold amplifier meets the input bandwidth requirements.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC08D1500 family of gigahertz-speed A/D converters. It is functionally similar to the ADC08D1000 but offers higher sampling rates. The device was originally introduced by National Semiconductor before being acquired by Texas Instruments. The 'CIYB' suffix denotes the commercial temperature range and the specific 128-lead HLQFP package type.

Analog To Digital Converters (ADC) Replacement Considerations

The SC08D1500 is documented as a domestic alternative compatible with the TI ADC08D1500. Other members of the family include the ADC08D1000 and the single-channel ADC081500. Verify pinout and register compatibility before substituting.
