LM258N Descrizione generale

Featuring two independent operational amplifiers, the LM258N is designed for high gain and internal frequency compensation. This versatile component is specifically tailored to operate from a single power supply over a wide range of voltages, with the added capability of functioning from split power supplies. Its low power supply current drain remains independent of the power supply voltage magnitude, making it an ideal choice for applications such as transducer amplifiers, DC gain blocks, and conventional op-amp circuits. Furthermore, the LM258N easily integrates into single power supply systems, including those utilizing the standard 3.3-V power supplies commonly found in digital systems. With the option of a chip-sized package using TI's DSBGA package technology, the LM258N offers a compact and efficient solution for electronic interfaces

Caratteristiche principali

Available in 8-bump DSBGA chip-sized package (see AN-1112, SNVA009)
Internally frequency compensated for unity gain
Large DC voltage gain: 100 dB
Wide bandwidth (unity gain): 1 MHz (temperature compensated)
Wide power supply range:
- Single supply: 3 V to 32 V
- Or dual supplies: ±1.5 V to ±16 V
Very low supply current drain (500 µA) essentially independent of supply voltage
Low input offset voltage: 2 mV
Input common-mode voltage range includes ground
Differential input voltage range equal to the power supply voltage
Large output voltage swing
Unique characteristics:
- In the Linear Mode the input common-mode voltage range includes ground and the output voltage can also swing to ground, even though operated from only a single power supply voltage
- The unity gain cross frequency is temperature compensated
- The input bias current is also temperature compensated
Advantages:
- Two internally compensated op amps
- Eliminates need for dual supplies
- Allows direct sensing near GND and V_OUT also goes to GND
- Compatible with all forms of logic
- Power drain suitable for battery operation
