ADS7881IPFBR

Analog To Digital Converters (ADC) Overview

The ADS7881IPFBR is a 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a digital supply voltage range of 2.7V to 5.25V and an analog supply voltage of 5V. The device supports a maximum sampling rate of 4 MSPS, achieving a conversion time of 0.25 µs. It features a parallel data interface and includes an internal reference. The component is housed in a 48-pin Thin Quad Flatpack (TQFP) package with dimensions of 7 mm x 7 mm. It is rated for operation within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a high-speed 12-bit SAR ADC architecture with a parallel output interface for direct microcontroller connectivity.
• Includes an on-chip precision voltage reference to minimize external component count and board space.
• Operates from a single 5V analog supply while accepting lower-voltage digital logic inputs.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring high-speed signal acquisition.
• Medical instrumentation such as ultrasound imaging and patient monitoring devices.
• Test and measurement equipment including oscilloscopes and data acquisition modules.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IPFBR to confirm the tape-and-reel packaging format and lead finish. Ensure the order quantity aligns with standard reel sizes provided by authorized distributors. Confirm RoHS compliance status and manufacturing origin through official datasheets or supplier documentation before finalizing procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution at 4 MSPS is required with a parallel interface. Compare against the ADS7883 if a smaller package size is needed, or the ADS7891 series for higher 14-bit resolution. Verify that the system power budget accommodates the specified 5V analog supply requirement.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS788x family of low-power, high-speed SAR ADCs from Texas Instruments. It shares architectural similarities with the ADS7882 and ADS7883 but offers a higher sampling rate of 4 MSPS compared to the 3 MSPS variants. The family is designed for applications demanding fast conversion times without excessive power consumption.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7882IPFBR serves as a functional substitute with identical pinout and specifications, except for a reduced sampling rate of 3 MSPS. The ADS7883 provides equivalent performance in a significantly smaller VQFN package. Verify thermal dissipation requirements when substituting into existing PCB layouts.
