The LTC6078HMS8#TRPBF is a fixed-gain precision low noise operational amplifier, ideal for applications that have stringent noise and power consumption requirements. It is designed to provide high performance in a compact form factor. This provides superior performance and superior value to engineers who need low noise, high precision amplifiers for their systems.

The LTC6078HMS8#TRPBF is an ultra-low-noise, low-power, bipolar-output, precision, differential-input operational amplifier. This device has a wide input common-mode range that helps it to keep the differential input voltage within the common-mode range of the amplifier. This makes it suitable for applications where the input voltages may range from +2 V to –2 V. The LTC6078HMS8#TRPBF also provides high-precision, low-noise operation with very low power dissipation. The amplifier has a wide bandwidth and excellent slew rate, ideal for applications that demand high-speed operation. Additionally, this amplifier features rail-to-rail inputs and outputs for enhanced linearity.

The amplifier has an internally fixed gain of 1 V/V and is designed to operate from a single supply voltage between 2.7 V to 5.5 V. It is available in several standard pin-out configurations, including the standard 8-pin SOIC package, and is specified over the extended industrial temperature range of –40 °C to +125 °C. This allows it to be used in extreme operational environments.

The LTC6078HMS8#TRPBF is suitable for a broad range of applications, such as instrumentation amplifiers, audio and RF signal conditioning, sample-and-hold circuits, thermocouple amplifiers, buffered voltage sources, low measurement systems, bridge transducers, encoders and transducers, as well as many other applications where low-noise performance and high-precision are important.

Working Principle

The LTC6078HMS8#TRPBF is a differential-input, single-ended output, high-precision, low-noise operational amplifier. The device consists of two main subcircuits: the buffered input stage and the main amplifier. The buffered input stage serves to ensure that the gain remains constant over a wide range of input levels. This stage is also responsible for providing the stable base for the main amplifier which provides the gain and noise immunity of the amplifier. The main amplifier is an output stage that is highly optimized for low noise performance. The amplifier also features a rail-to-rail output stage, which minimizes distortion.

The amplifier is operated from a single supply voltage and is configured in a single-ended configuration. The output voltage is a differential voltage, with the non-inverting input considered the reference. The output of the amplifier is a single-ended voltage (Vout) as seen at the output of the amplifier. The differential gain is equal to the voltage ratio between the non-inverting (VI+) and the inverting (VI–) inputs. This is the fixed gain of the amplifier and is specified as 1 V/V.

The fixed gain of the amplifier enables it to be used in a wide range of applications, such as instrumentation, audio, and telecommunication systems. The amplifier uses very low power, making it ideal for low power systems. The amplifier’s wide input common-mode range also makes it suitable for applications where the input levels may range from +2 V to –2 V. The amplifier features a wide bandwidth of 200 kHz and provides high-performance with low noise.
