ADS7890IPFBTG4

Analog To Digital Converters (ADC) Overview

The ADS7890IPFBTG4 is a 14-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a single pseudo-differential input channel and operates with an analog supply voltage of 5V and a digital supply range of 2.7V to 5.25V. The device supports a maximum sampling rate of 3M samples per second and utilizes a parallel data interface for high-speed data transfer. It is housed in a 48-TQFP package with dimensions of 7x7 mm, suitable for surface mount installation. The operational temperature range extends from -40°C to 85°C, ensuring reliability in industrial environments.

Analog To Digital Converters (ADC) Procurement Notes

Verify the component authenticity through authorized distributors or TI direct channels. Confirm the RoHS3 compliance status and check for any specific handling instructions related to moisture sensitivity level 2. Ensure the ordering suffix matches the required tape and reel or cut tape configuration for your assembly line needs.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance of moderate resolution and high speed is required for single-channel applications. Consider the parallel interface complexity against available GPIO resources. Evaluate the 5V analog supply requirement against system power constraints compared to lower voltage SAR ADC alternatives.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS789x family of high-speed, low-power ADCs from Texas Instruments. It shares architectural similarities with the ADS7891 but differs in specific pinout or feature configurations. The 'G4' suffix indicates lead-free construction compliant with environmental standards, while 'IPFBT' denotes the 48-TQFP package and tray/reel packaging type.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7891IPFBTG4 is a documented substitute within the same product family. Verify pin compatibility and functional equivalence before replacement. Other members of the ADS789x series may offer similar performance but require careful review of datasheet differences regarding interface timing and power consumption.
