Product details
Overview
LM7372IMAX/NOPB from Texas Instruments is a high-speed dual voltage-feedback operational amplifier optimized for video, xDSL, and pulse amplification. It delivers 3000 V/µs slew rate, 120 MHz gain bandwidth product, and 150 mA output current per channel at ±15 V supply, enabling high-fidelity signal distribution in professional video cameras and ADSL line drivers.
For engineers reviewing the LM7372IMAX/NOPB datasheet, LM7372IMAX/NOPB pinout, LM7372IMAX/NOPB application, or LM7372IMAX/NOPB equivalent, this page provides verified specifications, SO PowerPAD package details, harmonic distortion performance at 1 MHz, differential gain/phase accuracy, and real-world design context for high-current, low-distortion analog signal paths.
Technical Context
The LM7372IMAX/NOPB uses a complementary bipolar VIP™III process with class-AB output stages to achieve simultaneous high slew rate (3000 V/µs) and low harmonic distortion (−80 dBc HD2, −91 dBc HD3 at 1 MHz). Its voltage-feedback architecture supports stable operation at gains ≥ +2 or ≤ −1 without compensation.
It features rail-to-rail input common-mode range (±13 V at ±15 V supply), 85 dB open-loop gain, and thermal design optimized for the 8-pin SO PowerPAD package-where the exposed pad is internally tied to V− and requires PCB copper heatsinking for RθJA = 47°C/W.
Key Specifications

Pinout & Package
LM7372IMAX/NOPB is housed in an 8-pin SO PowerPAD (DDA) package (4.90 mm × 3.91 mm) with exposed thermal pad internally connected to V−. The pad must be soldered to PCB copper for thermal management.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Channel A output - capable of sourcing/sinking ±150 mA into 100 Ω load |
| 2 | −IN A | Channel A inverting input - high-impedance node for feedback network connection |
| 3 | +IN A | Channel A non-inverting input - accepts DC-coupled or AC-coupled signal sources |
| 4 | V− | Negative supply rail - internal die attach connects exposed PowerPAD to this pin |
| 5 | +IN B | Channel B non-inverting input - independent of Channel A; supports dual-path signal processing |
| 6 | −IN B | Channel B inverting input - used for differential or single-ended configurations per channel |
| 7 | OUT B | Channel B output - electrically identical to OUT A; enables dual-channel video or I/Q signal paths |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed dual op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS3202D | Higher slew rate (4700 V/µs), lower output current (±100 mA), no PowerPAD package | Better for ultrafast pulse shaping; less suitable for 100 Ω video or transformer drive | Select THS3202D when >3000 V/µs is required and thermal dissipation is managed via board layout |
| LMH6702MA | Wider GBW (1.8 GHz), higher supply current (18 mA), SOIC-8 (no thermal pad) | Superior small-signal bandwidth but higher distortion above 10 MHz; less robust at 150 mA load | Choose LMH6702MA for RF IF amplification where harmonic distortion below 10 MHz is not critical |
Compared with THS3202D and LMH6702MA, LM7372IMAX/NOPB uniquely balances 150 mA drive capability, −80 dBc HD2 at 1 MHz, and SO PowerPAD thermal performance-making it optimal for sustained high-current video and xDSL line driver applications where reliability under load is essential.

FAQ
What is the maximum output current capability of the LM7372IMAX/NOPB?
The LM7372IMAX/NOPB delivers ±150 mA per channel into resistive loads, verified at ±15 V supply with 100 Ω termination. This output current is sustained continuously without foldback or thermal shutdown when the SO PowerPAD package is properly heatsunk to PCB copper. The LM7372IMAX/NOPB maintains this drive capability across its full operating temperature range (−40°C to +85°C), making it suitable for transformer drivers and laser diode biasing where peak current demands exceed standard op-amp limits.
Does the LM7372IMAX/NOPB support single-supply operation?
Yes, the LM7372IMAX/NOPB operates from a total supply range of 9 V to 36 V, enabling true single-supply use (e.g., +12 V and GND) or split supplies (±5 V to ±15 V). At +12 V/GND, the input common-mode range extends to within 1.5 V of rails and output swing reaches >10 VP-P into 1 kΩ. However, full 150 mA output current and lowest distortion are specified at ±15 V; single-supply designs must verify headroom and load conditions per the LM7372IMAX/NOPB's recommended operating conditions table.
How is the exposed pad on the LM7372IMAX/NOPB SO PowerPAD package connected?
The exposed thermal pad on the LM7372IMAX/NOPB is internally connected to the V− pin (Pin 4) via conductive die attach material. It must be soldered to a PCB copper pour tied to the system V− net-not left floating-to achieve the specified RθJA of 47°C/W. TI documentation explicitly warns against connecting the pad to ground or other potentials, as doing so risks latch-up or parametric shift. The LM7372IMAX/NOPB's thermal performance depends entirely on this correct V− tie-down and adequate copper area (minimum 2 in²).
What harmonic distortion performance does the LM7372IMAX/NOPB deliver at 1 MHz?
At 1 MHz, 2 VP-P output, 100 Ω load, and ±12 V supply, the LM7372IMAX/NOPB achieves −80 dBc second-harmonic distortion (HD2) and −91 dBc third-harmonic distortion (HD3). These values are measured under AV = +2 configuration and represent typical performance across the industrial temperature range. This level of linearity meets stringent requirements for xDSL upstream transmitters and broadcast video amplifiers where multi-tone intermodulation must remain below −75 dBc.
Is the LM7372IMAX/NOPB pin-compatible with other TI dual op-amps like the LM7332?
No, the LM7372IMAX/NOPB is not pin-compatible with the LM7332 or other TI dual op-amps. Its 8-pin SO PowerPAD (DDA) pinout places V+ on Pin 8 and V− on Pin 4, with dedicated inputs and outputs per channel-distinct from LM7332's SOIC-8 layout (V+ on Pin 8, V− on Pin 4, but different IN/OUT assignments). Substituting LM7372IMAX/NOPB into an LM7332 footprint would cause incorrect biasing and functional failure. Always verify pin mapping using the LM7372IMAX/NOPB's official pin configuration diagram before board reuse.
