ADS7890IPFBRG4

Analog To Digital Converters (ADC) Overview

The ADS7890IPFBRG4 is a single-channel, 14-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with an analog supply voltage range of 2.7 V to 5.25 V and supports digital logic levels up to 5 V. The device features a parallel data interface and is housed in a 48-pin Thin-Fin Quad Flat Package (TFQFP) with dimensions of 7 mm x 7 mm. Key electrical specifications include a maximum linear error of 0.0092% and a longest conversion time of 0.365 µs. The component is RoHS compliant and rated for operation within a temperature range extending up to 85 °C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix RG4 indicates lead-free and RoHS compliance status against current manufacturer documentation. Confirm the TFQFP-48 package marking matches the physical component received. Ensure the operating environment remains within the specified 85 °C maximum junction temperature limit to maintain performance reliability.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-ended input channel with 14-bit resolution is required. The parallel interface necessitates multiple GPIO pins on the host microcontroller. Consider the 48-pin package size constraints during PCB layout planning compared to smaller footprint alternatives.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS789x family of high-speed, low-power SAR ADCs from Texas Instruments. The IPFB variant specifically denotes the industrial temperature grade and the plastic quad flat package construction. The RG4 suffix confirms the environmental compliance classification relative to earlier generations.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7891IPFBT serves as a functional substitute within the same family, offering identical pinout and interface characteristics. Verify that the specific tape-and-reel packaging requirements align with manufacturing assembly processes before substitution.
