ADS7800KPG4

Analog To Digital Converters (ADC) Overview

The ADS7800KPG4 is a 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a single-ended input channel and operates with parallel interface communication. The device supports sampling rates up to 333 kS/s and functions within an analog and digital supply voltage range of 4.75 V to 5.25 V. Key performance metrics include a signal-to-noise ratio of 73 dB, differential nonlinearity of ±0.75 LSB, and integral nonlinearity of ±0.5 LSB. It incorporates an internal reference and dissipates 135 mW of power. The component is housed in a 24-pin DIP package and operates across a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates an internal reference source to simplify circuit design.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring high-speed data acquisition.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'PG4' indicates a lead-free PDIP-24 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to procurement. Ensure the supplier provides valid traceability for this discontinued or legacy part number.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications necessitating a single-channel, 12-bit resolution with parallel output timing. Compare against serial interface alternatives if pin count reduction is required. Verify that the 333 kS/s sampling rate aligns with system bandwidth requirements and that the 5V logic levels are compatible with the host microcontroller.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7800 family of high-speed ADCs from Texas Instruments. It serves as a legacy alternative to newer serial interface models like the ADS7808. The PDIP-24 package distinguishes it from surface-mount variants such as the SOIC-24 version found in the ADS7800KUE4.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements may be limited due to the parallel interface architecture. Evaluate the ADS7808UBG4 for serial interface upgrades, noting the change from parallel to serial communication. Consult TI's official cross-reference tools for current availability and functional equivalents.
