Texas Instruments LM258AMDREP

The LM258AMDREP is a high-reliability, dual operational amplifier produced by Texas Instruments. This component is part of the LM258A series and is designed for operation in harsh environments. It consists of two independent, high-gain, frequency-compensated operational amplifiers that can operate from a single supply over a wide range of voltages (3 V to 30 V) or from dual supplies (±1.5 V to ±15 V). The device is particularly suited for applications requiring extended temperature performance, ranging from -55°C to 125°C.

• Controlled Baseline: Ensures consistent performance across different production lots.
• Extended Temperature Performance: Operates from -55°C to 125°C, making it suitable for harsh environments.
• Low Supply-Current Drain: Independent of the supply voltage magnitude, typically 0.7 mA.
• Wide Supply Range: Can operate from a single supply (3 V to 30 V) or dual supplies (±1.5 V to ±15 V).
• Low Input Bias and Offset Parameters: Input offset voltage of 2 mV, input offset current of 2 nA, and input bias current of 15 nA.
• Internal Frequency Compensation: Ensures stable operation without the need for external compensation components.
• Common-Mode Input Voltage Range Includes Ground: Allows direct sensing near ground.
• Enhanced Diminishing Manufacturing Sources (DMS) Support and Enhanced Product-Change Notification.
• Qualification Pedigree: Meets JEDEC and industry standards for reliable operation over an extended temperature range.

The LM258AMDREP is versatile and can be used in a variety of applications, including:

• Transducer Amplifiers: For amplifying signals from transducers in industrial and medical applications.
• DC Amplification Blocks: In single-supply-voltage systems, it can easily provide the required interface electronics without additional ±V supplies.
• Conventional Operational Amplifier Circuits: Suitable for comparator, differential amplification, and mathematical operations.
• Digital Systems: Can be operated directly from the standard 5-V supply used in digital systems, eliminating the need for additional ±5-V supplies).
