Linear - Amplifiers - Instrumentation, OP Amps, Buffer Amps
The LMH6639MAX/NOPB is a dual-channel, low power, low noise, wide bandwidth instrumentation amplifier with an adjustable gain. This amplifier uses high-performance, low-power technology to provide reliable signal amplification with high gain accuracy and low power consumption. It is ideal for applications such as video amplifiers, ultrasound systems, medical instrumentation, precision data acquisition, and general-purpose audio applications.
Features
- Low power – only 10 mW
- Wide bandwidth – up to 200 MHz
- Low noise – only 18 nV/√Hz
- Rail-to-rail input operation – operate with a single supply
- High gain accuracy – 0.01 %
- Adjustable gain – set with external resistors
Application Field
The LMH6639MAX/NOPB is a versatile and robust amplifier suitable for a variety of applications. It can be used in applications such as video signal processing, ultrasound systems, medical instrumentation, precision data acquisition, and general-purpose audio applications. The amplifier can also be used for DC signal amplification and signal conditioning. It is well suited for high-gain applications such as spectrometry systems, where stable gain and low noise operation are essential requirements.Working Principle
The LMH6639MAX/NOPB is a dual-channel instrumentation amplifier that uses a transconductance-type integrating structure to generate high-gain output. It is composed of two transimpedance (input) amplifiers followed by a unity gain summing amplifier. The transimpedance (input) amplifiers convert the differential input voltage into a transconductance signal that is then amplified to a higher level. The output of the transconductance amplifier is then summed by the unity gain summer, resulting in the overall gain of the amplifier.The LMH6639MAX/NOPB has an adjustable gain feature, which can be set via two external resistors. The output signal can be precisely adjusted from 0.1 V/V (10 dB) to 10 V/V (100 dB) by varying the resistors. The gain of the amplifier can also be programmed digitally via I2C or SPI.The LMH6639MAX/NOPB has excellent noise performance of 18 nV/√Hz due to the use of a low noise JFET input stage. The amplifier also has rail-to-rail input operation, allowing it to operate with a single supply over the complete input signal range. The amplifier also has a wide bandwidth of up to 200 MHz, and a maximum output drive of 25mA.The LMH6639MAX/NOPB is a robust and reliable amplifier, offering a high level of precision and performance in a wide range of applications. It is an ideal solution for video signal processing, ultrasound systems, medical instrumentation, precision data acquisition, and general-purpose audio applications.The specific data is subject to PDF, and the above content is for reference
