LME49740MAX/NOPB

The LME49740MAX/NOPB is a high-performance dual operational amplifier from TI (Burr-Brown lineage). It combines ultra-low input-referred noise, low distortion, and wide bandwidth, making it ideal for hi‑fi audio front-ends, DAC output buffers, active filters, and precision instrumentation.
Key points:
- Dual, precision op-amp with good overall linearity and fidelity.
- Suitable for single- or dual-supply operation over a broad voltage range; internally compensated for stable closed-loop gains.
- Very low noise and distortion, enabling clean amplification in sensitive circuits.
- MAX indicates a specific RoHS/lead-free packaging variant; NOPB confirms no lead (Pb-free).
Typical use:
- Audio preamps, line drivers, DAC buffering, instrumentation amplifiers, and high-accuracy signal conditioning.
Design notes:
- Provide proper power decoupling and layout to minimize noise and PSRR issues.
- Check the datasheet for exact specs (noise density, slew rate, gain-bandwidth, settling) at your intended supply and gain.

Pin count: 8 pins (8‑pin package, e.g., SOIC‑8/MSOP‑8).
Function: Dual low‑noise operational amplifier (two identical op‑amps in one package). Typical pinout (one common layout): Pin1 OUTA, Pin2 −IN A, Pin3 +IN A, Pin4 V−, Pin5 +IN B, Pin6 −IN B, Pin7 OUTB, Pin8 V+. NOPB indicates Pb‑free package. MAX is the specific package variant.

Manufacturer: Texas Instruments (TI).
Company type: TI is a U.S.-based multinational semiconductor company that designs and manufactures integrated circuits, including analog, digital, and embedded processing devices.

LME49740MAX/NOPB is a low-noise, high-precision op-amp suitable for:
- Audio: preamps, mixers, active filters, line drivers in pro/consumer gear
- Instrumentation and sensor front-ends: low-noise buffering, instrumentation amps, transimpedance stages
- Medical instrumentation: ECG/EEG front-ends, optical/sensor conditioning
- Test and measurement: precision signal conditioning, DA/AD front-ends
- General low-noise amplification where wide bandwidth and good DC precision are needed (buffers, gain stages, active filters)
Packaging “NOPB” just indicates Pb-free.

It uses an 8‑pin MSOP package (MSOP‑8), Pb‑free version indicated by NOPB.
