Linear - Amplifiers - Instrumentation, OP Amps, Buffer Amps

The LM833DG is a high-functionality operational amplifier (op amp) with capabilities that can be found in many high-end instrumentation and scientific op amps. Op amps are used in a variety of applications, from audio mixers to biasing circuits, and their formats, both small and large, are a popular choice for circuit delivery.

The LM833DG is an 8-pin dual-in-line package op amp that features low noise, high rates of operation, and low offset and easy-to-use current sense output. It uses two independent, complementary bipolar transistors to form a complementary symmetry amplifier circuit, which has relatively low input bias current, low offset voltage and low noise voltage.

In addition, it is capable of driving up to 6Vpp of output swings and slew rates of over 6250V/μs. It has a high output current of 25mA dynamic peak and 150mA static current, making it suitable for high-current loads and applications. Furthermore, it has good accuracy at various supply voltages and good thermal tracking capability.

The LM833DG is designed to be used in applications requiring low-noise, high-speed, and high-accuracy performance. Its wide supply voltage range of +/-18V and its low-noise performance of 5nV/√Hz make it an excellent choice for high-resolution measurements. Its low power consumption of 1.3mA/channel at single-supply bandwidth is ideal for low-power applications.

The LM833DG has a wide range of applications, including:

• High-precision voltage-to-current interface amplifiers
• Data acquisition systems
• Active filters
• High-precision signal conditioning
• Precision current sources
• Test and measurement equipment
• Controller modules
• Module amplifiers

The LM833DG features an innovative differential pair of bipolar transistors for a low noise amplifier. Each transistor has an intrinsic input impedance and a constant temperature coefficient. The intrinsic input impedance is balanced to the opposite side of the circuit, ensuring that the input stage is optically isolated from the rest of the circuit. This means that the signal coming through is unaffected by the high-frequency components of the signal. Moreover, the constant temperature coefficient helps to minimize errors caused by temperature variations.

The LM833DG also features output protection diodes and capacitor-coupled input circuits to help prevent damage to the amplifier or the rest of the circuitry in the event of an overload or overvoltage condition. Additionally, the device can be supplied with either bipolar or unipolar supplies that are optimized for various input ranges, allowing for flexibility in the design and use of the LM833DG.

Overall, the LM833DG is a great choice for applications requiring low-noise, high-speed, and high-accuracy performance. Its wide supply voltage range, low-noise performance, low power consumption, and wide range of applications make it a great option for any project and application, whether it is for audio mixers, modules, or test and measurement equipment.
