PAM8100RRR

Audio Special Purpose Overview

The PAM8100RRR is a stereo line driver manufactured by Diodes Incorporated, designed for single-supply electronics. It delivers up to 3 Vrms into a 2.5-kΩ load with a 5-V supply and 2 Vrms with a 3.3-V supply. The device eliminates output DC-blocking capacitors, reducing component count. It features differential inputs, adjustable gain from ±1 V/V to ±10 V/V via external resistors, and built-in mute control for pop-free operation. An internal and external undervoltage detector mutes the output during low voltage conditions.

Audio Special Purpose Feature Summary

• Eliminates output DC-blocking capacitors for reduced size and cost
• Low noise performance with SNR > 105 dB and THD+N < 0.005%
• Adjustable gain range of ±1 V/V to ±10 V/V using external resistors
• Built-in mute control and undervoltage protection for pop-free operation

Audio Special Purpose Procurement Notes

Verify the specific ordering suffix 'RRR' corresponds to the TSSOP-14 package shipped in a tape and reel configuration containing 3,000 units per reel. Confirm that the product status is acceptable for new designs, as the manufacturer indicates this model is obsolete and suggests the PAM8908 as an alternative.

Audio Special Purpose Replacement Considerations

The manufacturer explicitly recommends the PAM8908 as a replacement for new designs. Engineers should evaluate the PAM8908 datasheet to ensure pin compatibility and electrical parameter alignment before substituting the PAM8100RRR in existing schematics.
