Texas Instruments PCM3794ARHB
PCM3794ARHB variants from Texas Instruments
PCM3794ARHB Overview
What changes between part numbers, and what to check before you lock the BOM — Microcontrollers.
Key Features
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 2 distinct suffix patternsExamples: R, T. Decode suffix meaning in the ordering notes under the variant table.
Target Applications
- Microcontrollers — design-in and field replacement
- BOM scrub where only the base prefix is known but suffix is TBD
- Second-source checks when the original MPN is constrained
Ordering Variants
Compare 2 PCM3794ARHB part numbers by package, electrical parameters, lifecycle, and availability. Use RFQ for stock and lead-time confirmation.
| Part Number | Description | Manufacturer | Lifecycle | RoHS | Availability | Action |
|---|---|---|---|---|---|---|
| PCM3794ARHBR | Very Low-Power Stereo CODEC with HP Amplifier, notch filters, ALC and 3D Effects 32-VQFN -40 to 85 | Texas Instruments | Active | Compliant | In Stock | |
| PCM3794ARHBT | Very Low-Power Stereo CODEC with HP Amplifier, notch filters, ALC and 3D Effects 32-VQFN -40 to 85 | Texas Instruments | Active | Compliant | In Stock |

How to Choose the Right PCM3794ARHB Microcontrollers
Match the footprint first
Pull the exact package drawing for your MPN — base-number swaps fail most often at the footprint, not the schematic.
Electrical headroom
Compare voltage and current columns in the variant table. For PCM3794ARHB, a suffix with lower voltage or current rating will not survive the same circuit without recalculation.
Temp grade letter matters
Commercial (0–70 °C) and industrial (−40–85 °C+) suffixes look similar in the prefix — confirm ambient + self-heating, not just the first page of the datasheet.
Copy the full MPN
Do not BOM only "PCM3794ARHB" — include the full suffix (e.g. R, T). RFQ with reel/tube preference and required date code.
