<h2>Overview</h2><p>The LT1569CS8-7#TRPBF is an ultra-low-power, single-channel, lowpass unity-gain active filter. It integrates a low voltage, low-noise Op Amp with a switched capacitor lowpass filter, allowing it to operate on a single supply voltage as low as 1.8V while consuming only 1.8 uA. The device offers a temperature range of -40 to +85 °C, making it suitable for a wide range of applications.</p><h2>Application Field</h2><p>The LT1569CS8-7#TRPBF is designed for a variety of signal processing applications, including:</p><ul> <li>Low power audio, video and telecom applications.</li> <li>High frequency signal detection, such as notch, high-pass or band-pass filtering.</li> <li>RF-to-baseband conversion.</li> <li>Filtering of sensor signals from wireless medical implants.</li> <li>Motion/accelerometer sensing.</li></ul><p>The LT1569CS8-7#TRPBF also has applications in automotive, industrial and communications systems.</p><h2>Working Principle</h2><p>The LT1569CS8-7#TRPBF uses a switched capacitor lowpass filter with a gain of unity. The filter is comprised of four sections, or “quadrants”: an input stage, a notch filter, a high-pass filter, and a low-pass filter. The input stage is responsible for amplifying the input signal, while the notch and band-pass filters provide effective noise attenuation. The high-pass and low-pass filters are responsible for frequency selection and shaping the frequency response.</p><p>The active filter is easily configured to the desired frequency response characteristics. The user can adjust the gain and cut-off frequency of each section independently, allowing them to tailor the filter to their specific requirements. The device also offers a full CMOS logic interface, allowing it to be easily integrated into a wide range of systems.</p><p>The LT1569CS8-7#TRPBF is an ideal solution for low power, low noise filtering applications. Its single supply, rail to rail operation and low noise performance make it an ideal choice for sensitive applications such as medical implants, industrial and automotive systems, and more.</p>
