ADS7824PB

Analog To Digital Converters (ADC) Overview

The ADS7824PB is a 12-bit analog-to-digital converter (ADC) manufactured by Texas Instruments, housed in a 28-pin DIP package. It features four single-ended input channels and utilizes a successive approximation register (SAR) architecture. The device supports both parallel and SPI digital interfaces with a maximum sampling rate of 40 kS/s. It operates on a single 5V supply, consuming 50 mW of power. Key electrical specifications include a conversion time of 21 µs, an internal reference voltage, and differential/integral nonlinearity of ±1 LSB. The operational temperature range extends from -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'PB' against the manufacturer's current datasheet to confirm pinout compatibility and package dimensions. Ensure the ordered component matches the required operating temperature range and interface configuration. Cross-reference the part number with official Texas Instruments documentation to validate availability and revision status before integration into production designs.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution with four single-ended inputs is required. It is appropriate for applications needing moderate speed up to 40 kS/s. Consider the DIP package for prototyping or through-hole manufacturing needs. Evaluate power constraints as the device draws 50 mW during operation. Confirm interface compatibility with the host microcontroller's SPI or parallel bus capabilities.

Analog To Digital Converters (ADC) Part Context

The ADS7824 belongs to the ADS7824 family of 12-bit ADCs from Texas Instruments. This series offers a balance of resolution and speed for general-purpose data acquisition. The PB variant specifically denotes the dual in-line package format. It competes with other SAR ADCs offering similar channel counts and resolution levels in industrial and consumer electronics markets.

Analog To Digital Converters (ADC) Replacement Considerations

Check for direct pin-compatible replacements within the ADS7824 family, such as ADS7824N or ADS7824U, depending on the required package type. Verify that any substitute maintains the same 12-bit resolution, 4-channel configuration, and 40 kS/s sampling rate. Ensure interface compatibility remains unchanged.
