The MAX237CNG is an integrated circuit (IC) component manufactured by Maxim Integrated. It is a precision, high-performance, dual, linear, voltage-controlled resistor (VCR) intended for use in a variety of applications that require precise control of resistance.
The IC offers a wide operating voltage range from ±5V to ±18V, allowing for flexibility in different power supply configurations. It has two independent VCR channels, each capable of providing a low ±0.5% maximum nonlinearity error. This ensures accurate control over resistance across the entire operating range.
One of the key features of the MAX237CNG is its high bandwidth capability. With a -3dB bandwidth of 20MHz, it can handle high-frequency signals, making it suitable for applications involving audio, video, and other high-speed data signals. This high bandwidth ensures minimal distortion, maintaining signal integrity.
Another important feature is the IC's low noise performance. It achieves a low noise spectral density of 200nV/√Hz, which guarantees minimal noise interference, particularly in sensitive applications such as audio preamplifiers or low-noise amplifiers.
The MAX237CNG also provides excellent temperature stability. It offers a temperature coefficient of resistance (TCR) of 15ppm/°C, ensuring accurate and stable resistance values over a wide temperature range. This makes it well-suited for use in temperature-sensitive applications where precise control is required
