ADC0848BCV

Analog To Digital Converters (ADC) Overview

The ADC0848BCV is an 8-bit CMOS successive approximation analog-to-digital converter featuring an integrated 8-channel analog input multiplexer. Manufactured by Texas Instruments, this device operates with a single 5 VDC supply and supports a conversion time of up to 40 μs. It provides tri-state output latches for direct microprocessor interfacing without additional logic. The ADC0848BCV accommodates differential, pseudo-differential, and single-ended input configurations via software-selectable address lines. Designed for industrial environments, it functions within a temperature range of -40°C to +85°C and is housed in a 28-pin PLCC package.

Analog To Digital Converters (ADC) Feature Summary

• 8-Bit Resolution with 8-Channel Multiplexer
• Single 5 VDC Supply Operation (15 mW Power Consumption)
• Software Configurable Input Modes (Differential, Pseudo-Differential, Single-Ended)
• Tri-State Output Latches for Direct Microprocessor Bus Interface

Analog To Digital Converters (ADC) Applications

• Microprocessor-based data acquisition systems
• Industrial process control monitoring
• Battery-powered instrumentation requiring low power consumption
• Automotive ratiometric transducer interfaces

Analog To Digital Converters (ADC) Procurement Notes

Verify the marketing status before design implementation. The ADC0848BCV is classified as NRND (Not Recommended for New Designs), indicating it is in production only to support existing customers. TI does not recommend using this part in new designs. Confirm availability through authorized distributors and check for alternative active devices if long-term supply assurance is required.

Analog To Digital Converters (ADC) Selection Notes

Select the ADC0848BCV when an 8-bit resolution with an 8-channel multiplexer is required for legacy or specific microprocessor interfaces. Ensure the application can accommodate the 40 μs maximum conversion time and the 5 VDC supply voltage constraint. Verify that the source impedance remains below 1 kΩ to prevent errors from multiplexer leakage currents, or utilize external buffering for high-impedance sources.

Analog To Digital Converters (ADC) Part Context

The ADC0848BCV belongs to the ADC0844/ADC0848 family of 8-bit μP-compatible A/D converters. While the ADC0844 variant offers a 4-channel multiplexer, the ADC0848 expands this to 8 channels. Both share identical electrical characteristics, clocking, and interface protocols. The 'BCV' suffix denotes the commercial temperature range (-40°C to +85°C) and the 28-pin PLCC package format.

Analog To Digital Converters (ADC) Replacement Considerations

The datasheet lists the ADC0848BCV/NOPB as an active alternative within the same package type. For modern replacements, consider higher-resolution SAR ADCs from the ADS8xxx series or delta-sigma ADCs from the ADS1xxx series, depending on whether speed or precision is the primary requirement.
