MCP608-I/P

MCP608-I/P is a popular instrumentation amplifier used in various applications. It is an integrated circuit (IC) containing an in-amp and an output buffer, which makes it an ideal choice for a wide range of applications, such as medical instrumentation, data acquisition systems, voltage/current/pressure transducers, etc. In this article, we shall look at its application field and working principle in detail.

Application of MCP608-I/P

The MCP608-I/P is widely used in high-precision measurement and control applications due to its high precision and wide bandwidth. Its low input bias current and high common-mode rejection ratio make it suitable for measuring low level signals with a high degree of accuracy. It is particularly well-suited for use in applications involving precision low-level signal acquisition and buffering, such as:

• Medical instrumentation
• Test and measurement equipment
• Data acquisition systems
• Voltage/current/pressure transducers
• Signal filtering
• Video processing
• Industrial process monitoring and control
• Remote sensing

Working Principle of MCP608-I/P

The MCP608-I/P is an integrated circuit which contains an in-amp (actually an instrumentation amplifier) and an output buffer. The IC operates on a single supply and has a ±2.5V to ±18V power supply operating range. The amplifier has an input impedance of 3.9MΩ, an output impedance of 100Ω, and a gain bandwidth of 1MHz. The input bias current is commonly less than 5pA, making it ideal for measuring low-level signals.

The in-amp of the IC amplifies a differential input voltage and provides differential outputs with a gain of 1. The output buffer amplifies the differential outputs of the in-amp and provides a single-ended output. The output buffer has a gain of 0.5, a voltage offset of 350mV, and a slew rate of 10V/µs. All these features make the MCP608-I/P an ideal choice for buffering low-level signals.
