70 V/µs Slew Rate, 15 MHz GBP — Signal Chain Fit
The LM318MX/NOPB is a single-channel general-purpose operational amplifier from Texas Instruments, specified with a 70 V/µs slew rate and a 15 MHz gain-bandwidth product (GBP). The -3 dB bandwidth is also 15 MHz, so the GBP figure is the one that governs closed-loop gain-bandwidth trade-offs — at a gain of 10, the usable signal bandwidth is roughly 1.5 MHz before the open-loop gain rolls off. Input offset voltage is 4 mV maximum, and input bias current is 150 nA — both DC precision specs that matter when the amplifier drives a downstream ADC or a precision reference. Supply current is 5 mA, which is modest for this speed class; the supply range spans 10 V to 40 V total (single or split supplies), giving flexibility across ±5 V to ±20 V rails.
8-SOIC Package and 0°C to 70°C Temperature Grade
Housed in an 8-SOIC package (0.154-inch body width, 3.90 mm), the LM318MX/NOPB is a surface-mount device with a standard SOIC-8 footprint. The supplier device package is also 8-SOIC, so no footprint variation between the two identifiers. Operating temperature range is 0°C to 70°C — commercial grade. This limits deployment to indoor, temperature-controlled environments; not rated for industrial or automotive ambient extremes.
Active Lifecycle, ROHS3, and Packaging Options
Texas Instruments lists the LM318MX/NOPB as Active with ROHS3 compliance. Available in Tape & Reel (TR) or Cut Tape (CT) packaging — the TR option suits automated pick-and-place assembly, while CT works for prototype or low-volume builds. Sourced to order against an RFQ; availability and pricing confirmed at quote time.
