Part Audit Review
Review all available part information (MPN, package, pin count, description, properties). If no datasheet URL is already set, search the web for the official datasheet and update the part's Datasheet property with the URL. Then cross-check the schematic symbol, footprint, and pin descriptions against the datasheet. Summarize key specs and flag any mismatches.
Thought for 12 sec
I’ll audit the part metadata, locate and attach the official datasheet if needed, then verify the symbol, footprint, and pin descriptions against it.

Part Audit — THAT1512S08-U
Current part project metadata and library record Current schematic terminals and PCB footprint
Audit complete. The pinout and SOIC-8 footprint match the official datasheet; flagged issues are the incorrect “1510” description, blank Part Type/package metadata, unspecified pin types/descriptions, and a third-party rather than official datasheet URL. Full findings and key specifications are in Part Audit — THAT1512S08-U.

Metadata review
Table
| Field | Current value | Assessment |
|---|---|---|
| MPN | THAT1512S08-U | Correct; official ordering table identifies 1512S08-U as the THAT 1512 in SO8. The added THAT prefix is commonly used in distributor MPNs. |
| Manufacturer | THAT CORPORATION | Correct. |
| Description | PREAMP, MICROPHONE, SMD, 1510, SO8 | Partially incorrect/misleading: this is the 1512 variant, not the 1510. |
| Pin count | 8 | Correct. |
| Mount | Surface Mount | Correct. |
| Package | SO8 / 8-pin SOIC, 1.27 mm pitch | Footprint and suffix agree, but Package or Case Code is not populated in the available metadata. |
| Part Type | blank | Missing; should identify an audio/microphone preamplifier IC. |
| Datasheet URL | Third-party PDF mirror | Present, so no missing-URL update was required. An official manufacturer PDF is available and is preferable. |

Table
| Pin | Current name | Datasheet name | Result | Recommended description/type |
|---|---|---|---|---|
| 1 | RG1 | RG1 | Match | Gain-setting resistor terminal 1 — Analog/passive |
| 2 | -IN | -In | Match | Inverting audio input — Analog input |
| 3 | +IN | +In | Match | Non-inverting audio input — Analog input |
| 4 | V- | V- | Match | Negative supply — Power input |
| 5 | REF | Ref | Match | Output reference input — Analog input |
| 6 | OUT | Out | Match | Preamplifier output — Analog output |
| 7 | V+ | V+ | Match | Positive supply — Power input |
| 8 | RG2 | RG2 | Match | Gain-setting resistor terminal 2 — Analog/passive |
All eight pin numbers and names match the official SO8 pin assignment. However, every terminal currently has
Pin Type: Unspecified, and no Pin Description properties are populated.Footprint cross-check
The footprint is
SOIC127P600X173-8N with:- 8 rectangular SMD pads
- 1.27 mm lead pitch
- Pad size 0.65 × 1.525 mm
- Pad-row centers separated by 5.424 mm
- Fabrication body outline approximately 3.90 × 4.89 mm
- Pin-1 chamfer/marker aligned with pad 1
Official SO8 package limits:
- Pitch: 1.27 mm
- Body width: 3.81–3.99 mm
- Body length: 4.80–4.98 mm
- Overall lead span: 5.80–6.20 mm
- Package height: 1.35–1.73 mm
Assessment: the body outline and pitch match the official package. The land pattern is a normal IPC-style footprint extending beyond the physical lead span and appears suitable. No pad-count, pitch, or pin-1 orientation mismatch was found. The STEP model is attached, but exact 3D body/lead alignment was not dimensionally proven from the available structured data.
Key THAT 1512 specifications
- Function: low-noise, high-performance audio/microphone preamplifier
- Supply range: +5 to +20 V and -5 to -20 V
- Typical quiescent current: 6.0 mA per supply; 8.0 mA maximum at ±20 V
- Differential gain range: -6 to 64 dB
- Gain equation:
AV = 0.5 + 5 kΩ / RG - 0 dB gain resistor: 10 kΩ
- Typical input-voltage noise: 34 nV/√Hz at 0 dB; 1 nV/√Hz at 60 dB
- Typical slew rate: 19 V/µs
- Typical -3 dB bandwidth: 11 MHz at 0 dB; 1.6 MHz at 60 dB
- Typical output swing: ±13.3 V with 2 kΩ load on ±15 V supplies
- Minimum resistive load: 2 kΩ
- Maximum capacitive load: 300 pF
- Lead-free and RoHS compliant
Flagged issues
- Description variant mismatch: description says
1510, while the MPN is the THAT 1512 variant. - Missing Part Type: the part classification is blank.
- Missing package property: SO8 is implied by the MPN and footprint, but
Package or Case Codeis absent from available metadata. - Missing terminal metadata: all pins have unspecified electrical type and no pin descriptions.
- Datasheet provenance: the stored URL is a third-party mirror; the official THAT Corporation URL is available and preferred.
Overall conclusion
The electrically critical pin numbering, pin names, pin count, SO8 pitch, body outline, and pin-1 orientation are correct. The main deficiencies are metadata quality rather than pinout or footprint geometry.
