The LF353DG4 is an integrated circuit for use in linear, instrumentation, OP amps, and buffer amp applications. It provides excellent low noise performance, high input impedance, and high voltage gain. It is a dual high-speed variation of the general-purpose LF353 with additional features for power supply, input, and output protection.

The LF353DG4 is designed for use with a single power supply and its power is adjustable from 5 V to 22 V. The device is also designed to operate over a temperature range of -40°C to +85°C. Its maximum output current is rated at 6 mA. The LF353DG4 has a typical single supply voltage of 4 V to 18 V and a typical quiescent supply current of 4.5 mA.

The LF353DG4 consists of two internally matched, high-speed amplifiers that have a wide frequency range of DC to 40 MHz. It also has a high voltage gain of up to 200 dB with a lower noise performance than its single-supply counterpart. The amplifier provides 3-channel low-noise balanced input and low-distortion output.

The LF353DG4 is also provided with two internal rails that provide protection against output overvoltage and adverse operation of the amplifier under extreme conditions such as short-circuit, input overvoltage, and output overvoltage. The rail voltage is adjustable by the internal reference slides to maintain performance and it is also capable of externally monitoring the current output.

The LF353DG4 provides distortion-free operation and delivers low output noise (Typical <0.1uVrms). Its output stage uses a quadruple current source with an external capacitor for power supply current limit protection. The output stage also has an adjustable output offset for maintaining matching between the two amplifiers. In addition, the LF353DG4 has a built-in low-noise input compensation circuit that ensures stability across a wide range of frequencies.

The LF353DG4 is used in a wide range of applications such as audio preamps, line drivers, analog-digital converters, and RF amplifiers. It is provided with mounting hardware for use in open-loop applications. It is also useful in applications such as active filters, phase-shift networks, and instrumentation circuits. The LF353DG4 can also be used in single-supply applications like voltage followers, voltage references and comparators.

The LF353DG4 offers excellent performance when used in a range of different applications. It provides a wide range of features such as low noise, high input impedance and supply current limit protection. It is versatile, easy to mount and can deliver high levels of performance across a wide range of applications. Moreover, the LF353DG4 is a unique dual high-speed variation of the general-purpose LF353 amplifier and is ideal for use in high-performance and instrumentation applications.
