Product details
Overview
LM7372IMA-TI from Texas Instruments is a high-speed dual voltage-feedback operational amplifier optimized for video, xDSL, and pulse-amplifier applications. It delivers 3000 V/µs slew rate, 120 MHz gain bandwidth product, and 150 mA output current per channel at ±15 V supply, enabling clean signal distribution in HDTV and ADSL line drivers.
For engineers reviewing the LM7372IMA-TI datasheet, LM7372IMA-TI pinout, LM7372IMA-TI application, or LM7372IMA-TI equivalent, this page provides verified specifications, SOIC-8 PowerPAD package details, harmonic distortion performance at 1 MHz (−80 dBc HD2), differential gain/phase accuracy (0.01%/0.02°), and validated alternatives for high-current, low-distortion op-amp selection.
Technical Context
The LM7372IMA-TI uses a complementary bipolar VIP™III process with class-AB output stage, enabling simultaneous high slew rate (3000 V/µs) and low distortion (−91 dBc HD3 @ 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 @ ±15 V supply), 85 dB open-loop gain, and thermal design optimized for SO PowerPAD package with exposed pad tied to V−-enabling 47°C/W junction-to-ambient thermal resistance under proper PCB copper layout.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, high-output-current operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS3202D | Higher slew rate (4700 V/µs), lower output current (±110 mA), higher supply current (18 mA) | Better for ultrafast pulse shaping; less suitable for 100 Ω video distribution due to reduced drive capability | Select THS3202D when rise time <2 ns is required and load impedance ≥ 200 Ω |
| OPA2691U | Lower slew rate (2100 V/µs), higher GBW (320 MHz), lower distortion (−95 dBc HD3 @ 1 MHz) | Preferred for wideband IF amplification where bandwidth dominates over drive strength | Select OPA2691U for RF/IF signal chains requiring >200 MHz flat gain, not for video or line-driving loads |
Compared with THS3202D and OPA2691U, LM7372IMA-TI uniquely balances 150 mA output drive, 3000 V/µs slew rate, and −91 dBc HD3 in a thermally robust SOIC-8 PowerPAD package-making it optimal for xDSL line drivers and dual-channel video distribution where both current delivery and distortion performance are simultaneously critical.

FAQ
What is the maximum supply voltage for LM7372IMA-TI?
The LM7372IMA-TI supports a total supply voltage range of ±5 V to ±15 V, with absolute maximum rating of 36 V across V+ and V− terminals. Operation at ±15 V enables its full 150 mA output current and 3000 V/µs slew rate; at ±5 V, slew rate reduces to 700 V/µs but maintains low distortion for portable applications. Exceeding 36 V risks permanent damage per Absolute Maximum Ratings.
Does LM7372IMA-TI require external compensation for unity-gain stability?
No, the LM7372IMA-TI is not unity-gain stable. It is specified for stable operation only at closed-loop gains of +2 or greater (or −1 or less). Attempting unity-gain configuration will cause oscillation due to its 120 MHz gain-bandwidth product and internal compensation. For G = +1 applications, consider alternatives like OPA2677 or add external gain-setting resistors to meet minimum gain requirement.
How is thermal performance managed in the LM7372IMA-TI SOIC-8 PowerPAD package?
The LM7372IMA-TI uses an 8-pin SOIC with exposed PowerPAD (DDA package), achieving 47°C/W junction-to-ambient thermal resistance when the pad is soldered to a 2 in² copper area (top and bottom layers, 1 oz Cu). The die attach material connects internally to V−, so the pad must be tied to V− or left floating-not grounded-to avoid shorting. This thermal design enables safe operation at 578 mW total dissipation even at 85°C ambient.
What load impedance does LM7372IMA-TI drive while maintaining 0.01% differential gain?
The LM7372IMA-TI maintains 0.01% differential gain and 0.02° differential phase at 3.58 MHz when driving a 150 Ω terminated load with AV = +2 and 1 VPP input, as tested per SMPTE/ITU-R standards. It sustains this performance into 100 Ω loads in xDSL applications and 75 Ω coaxial lines in HDTV distribution-verified by TI's typical performance curves showing <0.02% gain error up to 10 MHz with 100 Ω termination.
Can LM7372IMA-TI operate from a single 12-V supply?
Yes, the LM7372IMA-TI supports single-supply operation down to +9 V (per Recommended Operating Conditions), making 12 V viable. However, input common-mode range is limited to V− + 1.5 V to V+ − 1.5 V, and output swing reduces to ~10 VPP into 1 kΩ. For optimal video or xDSL performance, split supplies (e.g., ±12 V) are recommended to maximize dynamic range and distortion performance as characterized in the datasheet.
