PGA2500IDBR

Overview

The PGA2500IDBR is a single-channel audio preamplifier manufactured by Texas Instruments, housed in a 28-SSOP surface-mount package. It operates on a supply voltage ranging from 4.75 V to 5.25 V with a typical operating current of 30 mA. The device provides a gain range of 0 dB and 10 dB to 65 dB in 1 dB steps. Key electrical specifications include a total harmonic distortion plus noise (THD+N) of 0.0002% and an input voltage noise density of 1.2 nV/sqrt Hz. It functions within a temperature range of -40°C to +85°C.

Feature Summary

Digital control interface for precise gain adjustment
Low-noise microphone preamplification architecture
High-fidelity audio signal processing capabilities

Applications

Professional audio mixing consoles
Broadcasting equipment front-ends
High-end recording interfaces

Procurement Notes

Verify the specific suffix 'IDBR' confirms the tape-and-reel packaging format distinct from tube variants like 'IDB'. Confirm RoHS compliance status and moisture sensitivity level requirements during storage and handling. Ensure the design supports the required digital control logic levels for gain setting.

Selection Notes

Select this component when low-noise performance and digital gain control are required for mono audio channels. Compare against other PGA2500 variants based on packaging preference (reel vs. tube). Verify that the 28-SSOP footprint matches the PCB layout constraints and thermal management requirements for the target application environment.

Part Context

This part belongs to the PGA2500 family of high-performance audio preamplifiers. It shares core functionality with variants such as PGA2500IDB and PGA2500IDBG4, differing primarily in packaging and manufacturing lot codes. The IDBR suffix specifically denotes the reel-packaged version suitable for automated surface-mount assembly processes.
