MAX5165NECM+T

The MAX5165NECM+T is a low-cost, low-power instrumentation amplifier (IA) that provides a high input impedance and a low output impedance. Its unique design combines a traditional IA amplifier circuit with a low-power, low-distortion transimpedance amplifier to provide a combined bias current and voltage significantly lower than a single-stage IA. The combined advantages of the two stages provide performance that is typically unobtainable in traditional IA designs.

Features:

• Wide supply voltage range: 5.0V to 36V
• Low supply current: 8mA
• CMRR: 78dB
• Signal-to-Noise Ratio: 81dB
• Input impedance: 100kΩ
• Output impedance: 5Ω
• Output voltage swing: 2.5V to 36V

Applications:

The MAX5165NECM+T is a perfect fit for applications that require superior performance from a low-power, low-cost instrumentation amplifier. Such applications include audio processing, medical instrumentation and industrial automation. It can also be used for signal conditioning and for building instrumentation amplifiers and transimpedance amplifiers. Furthermore, the low-power and low-distortion characteristics of the MAX5165NECM+T make it ideal for high-speed data acquisition and low-power applications.

Working principle:

The MAX5165NECM+T works on the principle of a transimpedance amplifier (TIA). A TIA is a type of differential amplifier that changes an input current to an output voltage. The MAX5165NECM+T takes two inputs, +I and -I, and amplifies them. It then converts the amplified differential voltage to a single-ended output. This output is then buffered and limited by the LM4562 op amp, which is the main output stage of the MAX5165NECM+T. The LM4562 has excellent linearity, noise, and power characteristics, so it is an ideal choice for this application. In addition, the MAX5165NECM+T features a high CMRR and low current draw, making it the perfect device for high-performance instrumentation amplifiers.
