High-speed dual op amp for heavy loads
The Texas Instruments LM7372MR-NS is a dual voltage-feedback operational amplifier built for applications that need to swing large voltages into capacitive or low-impedance loads at high speed. Its 3000 V/µs slew rate and 260 mA per-channel output current make it a natural fit for video distribution amplifiers, pin drivers in ATE, and waveform generators where settling time and drive strength matter more than DC precision. The 8-PowerSOIC package with an exposed pad (PowerPad) pulls heat out of the die when driving sustained output current — the pad must be soldered to a copper plane on the board.
260 mA output — driving cables and multiple loads
Each channel delivers 260 mA continuously.
Package and footprint
The LM7372MR-NS comes in an 8-lead PowerSOIC package (3.90 mm body width, 0.154" tall) with an exposed thermal pad on the bottom. The pad is the PowerPad — it must be soldered to a copper land on the PCB and connected to a ground plane for thermal relief. The pinout is standard for a dual op amp in SOIC-8, so it will fit the same footprint as many other dual op amps, but the thermal pad adds a ninth connection that is not present on a plain SOIC-8. Verify your PCB layout includes the pad land and the recommended via array under the part.
