The LM258DR from Texas Instruments is a dual general-purpose operational amplifier integrating two independent, high-gain, internally frequency-compensated op-amp channels. It operates from a total supply voltage of 3V to 30V and supports both single- and split-supply configurations for general analog signal-conditioning applications.
The LM258 provides a typical gain-bandwidth product of 0.7MHz (700kHz) and a typical slew rate of 0.3V/μs. Maximum input offset voltage at 25°C is 5mV, while typical common-mode rejection ratio is 80dB. Typical input voltage-noise density is approximately 40nV/√Hz at 1kHz.
Its input common-mode voltage range includes the negative supply rail, allowing direct sensing of signals close to ground in single-supply applications. Typical output-current capability is approximately 30mA, and the output can swing to within approximately 5mV of the negative supply rail under specified conditions.
The device uses a bipolar architecture with approximately 0.35mA typical quiescent current per channel and a maximum input bias current of approximately 150nA. The LM258 is rated for an extended -25°C to +85°C operating-temperature range, making it suitable for industrial and general-purpose control applications.
The specific LM258DR ordering option is supplied in an 8-pin SOIC (D) package measuring approximately 4.9 × 6mm. The “R” option uses 2500-piece large tape-and-reel packaging. It is RoHS and REACH compliant, uses NiPdAu lead finish, carries an MSL Level 1 rating, and is currently listed by TI as ACTIVE.
