Part Audit Review
IM70A135 Part Audit
PG-TLGA-5-2-V versus official PG-TLGA-5-5). The full specifications and comparison are in IM70A135 Part Audit.Table
| Field | Current state | Datasheet cross-check |
|---|---|---|
| Project/part name | IM70A135 | Matches product family name |
| Manufacturer Part Number | IM70A135 | Valid family/base identifier, but less specific than datasheet device type IM70A135V01 and ordering code IM70A135V01XTMA1 |
| Manufacturer | Not set | Should be Infineon Technologies |
| Description | Project description: “High Performance Analog XENSIV MEMS Microphone”; no explicit part property found | Functionally correct |
| Pin count | 5 terminals / 5 numbered pads | Correct |
| Package property | Not explicitly set | Datasheet package is PG-TLGA-5-5 |
| Datasheet URL | Was missing; updated during this audit | Now points to official Infineon PDF |
| Designator prefix | U? | Acceptable for an integrated MEMS microphone |
Table
| Pin | Current symbol name | Current type | Datasheet name/function | Result |
|---|---|---|---|---|
| 1 | VDD | Power In | VDD — Power supply | Match |
| 2 | GND | Power In | GND — Ground | Match; “Power In” is acceptable though Ground would be more semantically specific if supported |
| 3 | OUT_P | Output | Output + — Differential Output + | Match |
| 4 | OUT_N | Output | Output - — Differential Output - | Match |
| 5 | GND | Power In | GND — Ground | Match |
IFX-PG-TLGA-5-2-V.kicad_modPG-TLGA-5-5PG-TLGA-5-5.stpPG-TLGA-5-2-V, while the official package and 3D model are PG-TLGA-5-5. The actual geometry reviewed matches the IM70A135 datasheet, so this appears to be a naming/provenance mismatch rather than a land-pattern error.Table
| Parameter | Datasheet value |
|---|---|
| Interface | Analog differential |

| Supply, low-power mode | 1.52–1.8 V; 1.6 V typical |
| Absolute maximum VDD | 3.0 V |
| Current, normal mode | 170 µA typical, 230 µA maximum |
| Current, low-power mode | 70 µA typical, 80 µA maximum |
| Sensitivity | −38 dBV typical; −39 to −37 dBV |
| SNR | 70 dB(A) normal mode; 69 dB(A) low-power mode |
| Acoustic overload point | 135 dBSPL normal mode; 130 dBSPL low-power mode |
| Operating temperature | −40 to +85 °C |
| Storage temperature | −40 to +100 °C |
| Package | PG-TLGA-5-5 |
| Nominal dimensions | 3.50 × 2.65 × 1.00 mm |
