ADC0848BCVX

Analog To Digital Converters (ADC) Overview

The ADC0848BCVX is an 8-bit successive approximation analog-to-digital converter (ADC) manufactured by Texas Instruments. It integrates an 8-channel analog input multiplexer with software-configurable addressing logic, supporting single-ended, differential, and pseudo-differential operation modes. The device operates on a single 5 VDC supply, consuming approximately 15 mW of power. Key electrical specifications include a maximum conversion time of 40 μs, a total unadjusted error of ±1 LSB, and TRI-STATE output latches for direct microprocessor interface. It is housed in a 28-pin PLCC package and supports an operating temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrated 8-channel analog multiplexer with addressable inputs
• Software-selectable differential, pseudo-differential, or single-ended modes
• Direct TRI-STATE output latch interface for microprocessors
• Internal clock with 40 μs maximum conversion time

Analog To Digital Converters (ADC) Applications

• Microprocessor-based data acquisition systems
• Industrial process control monitoring
• Battery-powered instrumentation requiring low power consumption
• Multi-channel sensor signal conditioning

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix 'X' against the manufacturer's current packaging documentation to confirm reel quantity and tape specifications. Confirm RoHS compliance status as indicated in the latest Package Option Addendum, noting that non-NOPB variants may have different environmental classifications. Ensure the component source matches the active or NRND status defined in the official datasheet revision history.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-bit resolution and moderate sampling speed are sufficient for the application. The integrated multiplexer reduces external switching hardware compared to single-channel ADCs. Verify that the system can accommodate the 40 μs conversion latency. Ensure the analog input signals remain within the specified common-mode voltage limits relative to the 5 V supply rail to prevent diode conduction errors.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC0844/ADC0848 family of CMOS 8-bit A/D converters. The ADC0848 variant specifically provides eight analog input channels, whereas the ADC0844 offers four. Both share identical core architecture, including the successive approximation register and internal clocking mechanism. The BCV designation indicates the commercial temperature grade (-40°C to +85°C) and PLCC package style.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC0848BCV/NOPB is a lead-free alternative within the same package and specification profile. Direct pin-compatible replacements from other manufacturers require verification of logic voltage levels and multiplexer configuration compatibility.
