ADC0801LCN/NOPB

Analog To Digital Converters (ADC) Overview

The ADC0801LCN/NOPB is an 8-bit successive approximation analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a differential potentiometric ladder architecture and operates on a single 5-V supply. The device includes an on-chip clock generator, tri-state output latches, and logic inputs compatible with both MOS and TTL voltage levels. Designed for µP compatibility, it requires no additional interfacing logic. Key electrical specifications include a conversion time of 100 µs at a 640 kHz clock frequency, a total adjusted error of ±1/4 LSB, and an analog input voltage range of 0 V to 5 V.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'LCN' corresponds to the PDIP package and the -40°C to +85°C operating temperature range as defined in the datasheet. Confirm that the NOPB suffix indicates lead-free and RoHS compliance. Ensure the source documentation explicitly lists this exact part number to avoid confusion with other variants in the ADC080x family.

Analog To Digital Converters (ADC) Selection Notes

Select the ADC0801LCN/NOPB when differential analog inputs are required to offset zero-input voltage or improve noise immunity. This model provides ±1/4 LSB accuracy with full-scale adjustment. Choose this component over non-differential variants if the application involves signals referenced to a ground different from the system ground or requires higher common-mode rejection capabilities.

Analog To Digital Converters (ADC) Part Context

The ADC0801LCN/NOPB belongs to the ADC080x series, which includes the ADC0801 through ADC0805. These devices share a similar CMOS architecture and pinout structure but differ in accuracy specifications and internal reference configurations. The ADC0801 specifically offers the highest accuracy within the basic series at ±1/4 LSB.

Analog To Digital Converters (ADC) Replacement Considerations

Direct functional substitutes within the same family include the ADC0802, ADC0803, ADC0804, and ADC0805. Note that these alternatives have different accuracy ratings (±1/2 LSB or ±1 LSB) and may require different VREF/2 connections. Verify package compatibility and temperature range requirements before substitution.
