Device Overview
Texas Instruments LM4562MAX/NOPB is an exact-order audio amplifier supplied in SOIC-8. For substitution or design review, the strongest comparison points are Channels (2), Gain-bandwidth product (55 MHz), Voltage-noise density (2.7 nV/??z).
Selection-Critical Data
| Parameter | Confirmed Data | Why It Matters |
|---|---|---|
| Channels | 2 | Defines the number or arrangement of parallel signal/control paths and therefore the resources a replacement must provide. |
| Gain-bandwidth product | 55 MHz | Sets the signal-level gain budget and must be compared at matching frequency, mode and bias conditions. |
| Voltage-noise density | 2.7 nV/??z | Defines the electrical voltage envelope that must cover the intended operating or stress level. |
| Supply range | ±2.5 V to ±17 V | Defines DC current demand and therefore contributes to power consumption, rail loading and thermal burden. |
| Exact Package | SOIC-8 | Determines PCB footprint, pinout, mechanical assembly and orderable-variant compatibility. |
| Device Function | audio amplifier | Defines the device function or architecture that a compatible replacement must preserve before secondary ratings are compared. |
Analog Selection Notes
The channels is 2; this defines the number or arrangement of parallel signal/control paths and therefore the resources a replacement must provide. At 55 MHz, the gain-bandwidth product sets the signal-level gain budget and must be compared at matching frequency, mode and bias conditions. At audio amplifier, the device function defines the device function or architecture that a compatible replacement must preserve before secondary ratings are compared.
SOIC-8 is the stated exact package value. Determines PCB footprint, pinout, mechanical assembly and orderable-variant compatibility.
For voltage-noise density, 2.7 nV/??z is the approved value. Defines the electrical voltage envelope that must cover the intended operating or stress level. The supply range is +/-2.5 V to +/-17 V; this defines compatibility with the available board supply rail and the voltage range over which the stated device function is intended to operate.
