ADC0848CCVX/NOPB

Analog To Digital Converters (ADC) Overview

The ADC0848CCVX/NOPB is an 8-bit analog-to-digital converter manufactured by Texas Instruments, originally part of the National Semiconductor portfolio. It features a successive approximation register (SAR) architecture with an integrated 8-channel multiplexer. The device operates on a single 5 V supply for both analog and digital sections, supporting parallel microprocessor-compatible interfaces. Key electrical specifications include a sampling rate of 25 kS/s, differential/pseudo-differential/single-ended input types, and an external reference requirement. It is housed in a 28-PLCC package and functions within a commercial temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

This component is listed as obsolete or discontinued by the manufacturer. Availability is limited to existing stock from distributors or secondary market sources. Verification of authenticity and lot traceability is critical due to the end-of-life status. Buyers should confirm the specific suffix 'NOPB' indicates lead-free compliance and check for moisture sensitivity handling requirements before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-bit resolution with an integrated multiplexer is required for cost-sensitive applications. It is suitable for systems where a parallel interface is preferred over serial alternatives like SPI or I2C. Consider the 25 kS/s sampling limit and 5 V voltage domain constraints. For newer designs, evaluate modern equivalents with higher resolution or lower power consumption if system requirements allow.

Analog To Digital Converters (ADC) Part Context

The ADC0848 belongs to the legacy National Semiconductor ADC08xx family, now managed by Texas Instruments following their acquisition. The 'NOPB' suffix denotes a non-leaded, Pb-free package compliant with RoHS standards. This specific variant represents the tape-and-reel version (indicated by 'X') of the standard PLCC package, designed for automated surface-mount assembly processes.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-to-pin replacements may be limited due to the obsolete status. Potential substitutes include other 8-bit SAR ADCs with integrated multiplexers from manufacturers like Microchip or Analog Devices, though interface compatibility must be verified. Designers should assess whether upgrading to a 12-bit or serial-interface ADC is feasible for new implementations.
