ADC081000CIYB

Analog To Digital Converters (ADC) Overview

The ADC081000CIYB is an 8-bit, 1 GSPS analog-to-digital converter from Texas Instruments. It operates on a single +1.9V supply and consumes approximately 1.45 W at maximum sampling rates. The device utilizes a folding and interpolating architecture with an internal sample-and-hold amplifier to ensure no missing codes across the operating temperature range. It features differential LVDS outputs compliant with IEEE 1596.3-1996 standards, excluding reduced common mode voltage specifications. Key electrical parameters include a typical ENOB of 7.5 bits at 500 MHz input, ±0.25 LSB DNL, and a full power bandwidth of 1.7 GHz.

Analog To Digital Converters (ADC) Feature Summary

• High-speed 8-bit resolution with a minimum conversion rate of 1 GSPS and a maximum of 1.6 GSPS.
• Low power consumption of 1.45 W (typical) in operation and less than 10 mW in standby mode.
• Integrated self-calibration scheme ensuring no missing codes over the industrial temperature range.
• Differential LVDS digital outputs with a 1:2 demultiplexer reducing per-bus data rates to half the sampling frequency.

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 CIYB against current manufacturer availability lists, as high-speed ADCs often have limited production lifecycles or specific package constraints. Confirm that the HLQFP-128 thermal pad soldering requirements are met during assembly to maintain rated performance. Check for updated datasheet revisions (SNAS209G) to ensure compliance with latest electrical characteristics and absolute maximum ratings.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-bit resolution is sufficient for applications requiring sampling rates up to 1.6 GSPS. Ensure the system design supports a single +1.9V analog and digital supply voltage. Verify that the PCB layout can accommodate the 128-lead HLQFP package and provides adequate thermal management for 1.45 W dissipation. Confirm compatibility with LVDS signaling standards for the digital interface.

Analog To Digital Converters (ADC) Part Context

The ADC081000 series represents Texas Instruments' high-performance, low-power CMOS analog-to-digital converters designed for demanding signal processing tasks. The CIYB variant specifically denotes the 128-lead High-Performance Low-Profile Quad Flat Package (HLQFP). This family is distinguished by its unique folding and interpolating architecture, which enables flat dynamic parameter responses beyond the Nyquist frequency.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate other Texas Instruments high-speed ADCs based on resolution, sampling rate, and interface compatibility if direct replacement is required.
