ADI LT6011CS8 Dual 135µA Rail-To-Rail Output Precision Operational Amplifier

Shenzhen Mingjiada Electronics Co., Ltd, as a world-renowned authorised independent distributor of electronic components, is now supplying the ADI LT6011CS8 dual-channel 135µA rail-to-rail output precision operational amplifiers, which, with their ultra-low power consumption, high accuracy and rail-to-rail output characteristics, are ideal for applications such as industrial control, medical equipment and test and measurement.

Product Description Of LT6011CS8
LT6011CS8 Operational Amplifier combine low noise and high precision input performance with low power consumption and rail-to-rail output swing.

Input offset voltage is trimmed to less than 60µV. The low drift and excellent long-term stability guarantee a high accuracy over temperature and time. The 300pA maximum input bias current and 120dB minimum voltage gain further maintain this precision over operating conditions.

LT6011CS8 work on any power supply voltage from 2.7V to 36V and draw only 135µA of supply current on a 5V supply. The output swings to within 40mV of either supply rail, making the amplifier a good choice for low voltage single supply applications.

LT6011CS8 is specified at 5V and ±15V supplies and from –40°C to 85°C. The LT6011CS8 (dual) is available in SO-8 and space saving 3mm x 3mm DFN packages.

The LT6011CS8 offers significant advantages:
Power Supply Characteristics: The LT6011CS8 supports a single-supply supply from 2.7V to 36V or a dual-supply supply from ±1.35V to ±18V, a wide power supply range that enables it to adapt to a variety of power supply environments ranging from battery-powered portable devices to industrial-grade systems. Notably, the device maintains stable performance parameters over such a wide supply range, which is especially important for applications that require operation under varying voltage conditions.

Quiescent Current: Each amplifier channel consumes only 135µA of quiescent current, a feature that gives the LT6011CS8 a significant advantage in power-sensitive applications. Compared to traditional precision operational amplifiers that typically require milliamp-level operating currents, the LT6011CS8 significantly reduces power consumption while maintaining high accuracy, extending the runtime of battery-powered devices.

Noise Performance: The LT6011CS8 devices offer an input voltage noise density of 14nV/√Hz (at 1kHz), a metric that is critical for precision signal conditioning circuits, especially when dealing with weak sensor signals. The low noise characteristics combined with the high precision input enable the LT6011CS8 to accurately amplify microvolt signals without introducing significant noise.

Input Characteristics: The LT6011CS8 features an input offset voltage of 35µV and an input bias current of only 150pA, parameters that ensure the accuracy and stability of the signal amplification process. The low input bias current makes it suitable for direct interface with high impedance transducers without concern for measurement errors caused by the amplifier input current.

Superior accuracy performance: The LT6011CS8 features a maximum out-of-phase voltage of only 60µV, a maximum input bias current of 300pA, and a maximum VOS drift of 0.8µV/°C, ensuring long-term stability and high-precision signal processing.

Rail-to-rail output swing: The LT6011CS8 delivers maximum output signal amplitude over the full supply voltage range for improved dynamic range

Low noise design: With an input noise voltage of 14nV/√Hz, the LT6011CS8 is suitable for high sensitivity signal amplification applications.

Wide temperature operating range: -40°C to 85°C operating temperature range to meet the needs of industrial grade applications
