Package and board integration
The LM258DR ships in an 8-SOIC package (0.154", 3.90 mm width) with surface-mount termination — the 1.27 mm pitch is a standard footprint that routes cleanly on a two-layer board without micro-vias. Supplier device package is 8-SOIC, and the part is available on Tape & Reel or Cut Tape for both automated pick-and-place and prototype builds.
Key parametrics and what they mean for the BOM
Two general-purpose op-amp circuits in one package, each drawing 500 µA supply current — total 1 mA for the dual channel, keeping the power budget tight in multi-stage signal chains. Gain bandwidth product of 700 kHz with a 0.3 V/µs slew rate sets the usable signal bandwidth — for a unity-gain buffer, expect clean response up to roughly 100 kHz before slew-rate limiting distorts the output. Input offset voltage is 3 mV max, input bias current 20 nA — adequate for general-purpose DC coupling where the signal is above a few millivolts and source impedance is under 10 kΩ. Each output can source or sink 40 mA, enough to drive a small relay coil, an LED indicator, or the input of a following ADC without a separate buffer stage.
Supply rail and temperature range
Operates from a single supply as low as 3 V up to 32 V, or split supplies — the wide span means it fits into 5 V or 24 V industrial rails without a secondary regulator. Rated for -25°C to 85°C ambient, covering commercial and most indoor industrial environments — not qualified for automotive under-hood or extended industrial beyond 85°C.
Lifecycle and sourcing
Sourced through independent distribution channels; pricing and lead time are confirmed at quote against the BOM quantity.
