Key Featrues
High Frequency Operation: The LT1568 supports center frequencies up to 10MHz on a single 3V supply, making it suitable for high-frequency applications such as video signal processing and RF filtering. This feature enhances its versatility in demanding environments.
Easy Configuration: A single resistor value sets the lowpass cutoff frequency (200kHz to 5MHz), while unequal resistor values extend the cutoff frequency up to 10MHz. This simplifies design and reduces the need for complex external components, improving efficiency in system integration.
Low Noise and High SNR: With a Signal-to-Noise Ratio (SNR) of 92dB at 2MHz and 2V peak-to-peak, the LT1568 ensures clean signal processing, making it ideal for applications requiring high precision, such as antialiasing and reconstruction filters.
Flexible Filter Configurations: The LT1568 can be configured as a single 4-pole lowpass filter or a matched pair of 2-pole lowpass filters, and it can also operate as a bandpass filter. This flexibility allows it to address diverse use cases, including dual or I/Q channel processing.
Rail-to-Rail Operation: The device supports rail-to-rail input and output voltages, enabling full utilization of the supply voltage range. This feature enhances performance in low-voltage applications and ensures compatibility with a wide range of signal levels.
