STMICROELECTRONICS LM2904AHYQ6T Operational Amplifier, 2 Channels, 1.1 MHz, 0.6 V/µs, 3V to 30V, WFDFN-EP, 8 Pins

LM2904AHYQ6T is a low-power, dual-operational amplifier. This circuit consists of two independent, high-gain operational amplifiers (op-amps) that have frequency compensation implemented internally. It is designed specifically for automotive and industrial control systems. The circuit operates 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 from the standard 5V which is used in logic systems and easily provides the required interface electronics without requiring any additional power supply. 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 a single power supply.

• Frequency compensation implemented internally, large output voltage swing 0V to [(VCC +) -1.5V]
• Very low supply current/amplifier, essentially independent of supply voltage
• Input common-mode voltage range includes negative rail
• Differential input voltage range equal to the power supply voltage
• Input offset voltage is 1mV typical (VCC+ = 5V, VCC- = ground, VO = 1.4V, Tamb = 25°C)
• Input bias current is 20nA typical (VCC+ = 5V, VCC- = ground, VO = 1.4V, Tamb = 25°C)
• Input offset current is 2nA typical (VCC+ = 5V, VCC- = ground, VO = 1.4V, Tamb = 25°C)
• Gain bandwidth product is 1.1MHz typ (f = 100KHz, VCC + = 30V, Vin = 10mV, RL = 2Kohm)
• Equivalent input noise voltage is 55nV/? Hz typ at (f = 1KHz, RS = 100 ohm, VCC + = 30V)
• Operating temperature range from -40°C to 150°C, DFN8 package
