Texas Instruments LM258D

Overview

LM258D from Texas Instruments is a dual operational amplifier designed for cost-sensitive industrial and consumer applications requiring rail-to-rail input capability, 3 V to 32 V single-supply operation, and stable performance across –25°C to +85°C ambient temperature. It delivers 0.7 MHz unity-gain bandwidth, 0.3 V/µs slew rate, and 7 mV maximum input offset voltage at 25°C, commonly used in motor control feedback loops and power supply monitoring circuits.

For engineers reviewing the LM258D datasheet, LM258D pinout, LM258D application, or LM258D equivalent, key selection criteria include its guaranteed common-mode input range extending to ground, output swing within 20 mV of negative rail at light load, and compatibility with SOIC-8 packaging for legacy board designs.

Technical Context

The LM258D implements a standard two-stage CMOS-compatible bipolar op-amp architecture with internal frequency compensation for unity-gain stability. Its input stage uses matched PNP transistors enabling rail-to-ground common-mode operation, while the output stage provides class-AB push-pull drive capable of sourcing/sinking ±20 mA.

It operates over a wide supply range (3 V–32 V) with quiescent current of 350 µA per amplifier (typical), supports differential input voltages up to ±32 V, and maintains open-loop gain ≥25 V/mV under recommended conditions - making it suitable for precision DC-coupled amplification and active filtering in non-critical timing applications.

FAQ

What is the maximum supply voltage for LM258D?

The LM258D supports a maximum supply voltage of 32 V across V+ and V– pins. This rating applies to both single-supply (e.g., V+ = 32 V, V– = 0 V) and split-supply (e.g., V+ = ±16 V) configurations. Exceeding this limit risks permanent damage, as confirmed in the Absolute Maximum Ratings table of the official LM258 datasheet. Always verify layout decoupling and thermal derating when operating near 32 V in the LM258D design.

Does LM258D support rail-to-rail input?

Yes, the LM258D supports rail-to-rail input common-mode range down to the negative supply rail (V–), including ground in single-supply operation. This is explicitly specified in the Recommended Operating Conditions table: VCM minimum = V–. However, its output is not rail-to-rail - it swings within ~20 mV of V– and ~1.5 V of V+ under typical loads. This behavior is documented in the Electrical Characteristics section for LM258/LM258A.

What is the input offset voltage specification for LM258D?

The LM258D has a maximum input offset voltage of 7 mV at 25°C, as stated in the LM258 Electrical Characteristics table (Section 7.9). At full temperature range (–25°C to +85°C), the offset may increase slightly but remains bounded per characterization data. This value is higher than the LM258A (3 mV max), confirming LM258D as the standard-grade variant optimized for cost over ultra-precision.

Can LM258D drive capacitive loads?

The LM258D is characterized to safely drive up to 100 pF capacitive loads without oscillation, as noted in the "Capacitive load drive" parameter in Section 7.9 of the datasheet. For larger loads (e.g., >200 pF), external isolation resistance (e.g., 50–100 Ω in series with the output) is recommended to maintain phase margin. This limitation stems from its internal compensation and is consistent across the LM358/LM258 family.

Is LM258D pin-compatible with LM358?

Yes, LM258D is pin-compatible with LM358 in SOIC-8 packaging - both share identical pinout (OUT1, IN1–, IN1+, V–, IN2+, IN2–, OUT2, V+). They also match in footprint, thermal metrics, and absolute maximum ratings. However, LM258D is rated for –25°C to +85°C operation, whereas standard LM358 is rated 0°C to +70°C - a key distinction for industrial deployment where extended temperature tolerance is required.
