LTC1065IN8#PBF Low Power, 8th Order Lowpass Filter

The LTC1065IN8#PBF is a high-performance, 8th order lowpass Bessel filter that boasts a fixed cutoff frequency of 100kHz. Manufactured by Linear Technology, a leader in analog integrated circuits, this filter is designed to provide optimum performance in a variety of signal processing applications. The LTC1065 is part of a family of filters that are known for their low noise and low power consumption, making them ideal for battery-powered and portable devices.

This filter comes in a compact 8-pin PDIP package, which is suitable for space-constrained applications. The LTC1065IN8#PBF operates with a single 5V power supply, which allows for easy integration into existing designs without the need for additional power regulation. It also features a low power consumption of only 2.5mA, which is beneficial for extending battery life in portable applications.

The LTC1065IN8#PBF's Bessel filter characteristic is known for its linear phase response, which preserves the wave shape of filtered signals, particularly important in data communications, medical electronics, and instrumentation. The linear phase response ensures minimal group delay variation, which is critical for applications involving pulse or complex signal processing.

With its 8th order filter design, the LTC1065IN8#PBF provides a sharp cutoff, ensuring strong attenuation of frequencies beyond the 100kHz cutoff point. This makes it highly effective in removing unwanted high-frequency noise while maintaining the integrity of the desired signal within the passband.

Additionally, the LTC1065IN8#PBF includes a shutdown feature that reduces power consumption to 20µA, further enhancing its appeal for power-sensitive applications. When in shutdown mode, the filter's output is placed in a high impedance state, allowing for additional power savings.

In summary, the LTC1065IN8#PBF from Linear Technology is a versatile, low power, 8th order lowpass filter that delivers high-performance signal processing capabilities with the added benefits of a low power shutdown mode and a linear phase Bessel response. Its compact size and single-supply operation make it a convenient choice for a wide range of applications, from portable electronics to complex signal processing systems.
