LM258APT

LM258APT is a low-power dual-operational amplifier. This circuit consists of two independent, high gain, internally frequency-compensated op-amps, specifically designed to operate from a single power supply over a wide range of voltages. The low-power supply drain is independent of the magnitude of the power supply voltage. Application areas include transducer amplifiers, DC gain blocks and all the conventional op amp circuits, which can now be more easily implemented in single power supply systems. For example, these circuits can be directly supplied with the standard 5V, which is used in logic systems and will easily provide the required interface electronics with no additional power supply. In linear mode, the input common-mode voltage range includes ground and the output voltage can also swing to the ground, even though operated from only a single power supply voltage.

• Frequency compensation implemented internally
• Very low supply current per channel essentially independent of supply voltage
• Input common-mode voltage range includes negative rails
• Differential input voltage range equal to the power supply voltage
• Large output voltage swing 0V to (VCC+- 1.5V)
• Input offset voltage is 1mV typical at (Vo = 1.4V, Tamb = 25°C)
• Input bias current is 20nA typical at (Vo = 1.4V, Tamb = 25°C)
• Large signal voltage gain is 100V/mV typ at (VCC+ = 15V, RL = 2kohm, Vo = 1.4V to 11.4V)
• Gain bandwidth product is 1.1MHz typ at (VCC+ = 30V, f = 100kHz, Vin = 10mV)
• Operating temperature range from -40°C to 105°C
