ADC0802LCWM/NOPB

Analog To Digital Converters (ADC) Overview

The ADC0802LCWM/NOPB is an 8-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a single differential input and operates with a sampling rate of 10 kSPS. The device utilizes a parallel data interface for output transmission. It is housed in a 20-SOIC surface-mount package with a width of 7.50 mm. Electrical specifications include an analog supply voltage range of 4.5V to 6.3V and a digital supply voltage range of 4.5V to 6.3V. The component supports an external reference type derived from the power supply and functions within a commercial operating temperature range of 0°C to 70°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix configuration against the manufacturer's current datasheet to ensure compatibility with required packaging options, such as tube versus tape-and-reel formats. Confirm that the lead time aligns with project schedules, as standard delivery periods may vary based on manufacturing availability. Ensure compliance with RoHS3 directives if environmental regulations apply to the final assembly. Cross-reference the distributor part number with the original equipment manufacturer identifier to prevent sourcing errors during procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-bit resolution and 10 kSPS throughput are sufficient for the application requirements. Consider the 20-SOIC package dimensions for PCB layout constraints. Evaluate the need for differential inputs versus single-ended alternatives if noise performance is critical. Verify that the available supply voltage ranges match the system's power design. Assess whether the parallel interface complexity justifies the use of this device over serial alternatives.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADC080x family of analog-to-digital converters produced by Texas Instruments. The family includes variants such as the ADC0801, ADC0802, and ADC0804, which share similar architectural foundations but differ in pinouts and specific electrical characteristics. The NOPB suffix indicates a lead-free and halogen-free compliant version of the standard ADC0802LCWM component. This lineage provides designers with established, reliable conversion solutions for general-purpose applications.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC0804LCWM/NOPB serves as a functional substitute within the same product family, offering identical 8-bit SAR architecture and 10 kSPS performance. Designers should verify pinout compatibility and ensure that any differences in internal circuitry do not affect system timing or signal integrity before implementing the replacement.
