The LTC1062CSW#TRPBF operates in the range from 100 kHz to 500 MHz and provides a wide range of active filter applications in both transmit and receive signal path substations. The device is a low noise and low power monolithic, multi-stage active filter specifically developed for a wide range of professional audio frequency applications.

The device can be used to perform linear signal transformation and filtering operations including band-pass, low-pass or high-pass, notch, and all-pass filter modes. The filter design is based on a hybrid combination of shallow-slope switched-capacitor (SC) and continuous-time (CT) filter blocks, using carefully selected circuit elements. The design topology of the LTC1062CSW#TRPBF offers the advantages of low complexity, low power consumption, low noise, and high gain.

The LTC1062CSW#TRPBF features a wide range of operating frequencies and signal configurations, allowing for a variety of custom filter designs. The device includes a low-noise, low-power preamplifier and driver stage with gain-bandwidth control. The pre-amp and driver circuit is optimized for high signal-to-noise performance and can be configured for gain values from 0dB to +12dB. The low-noise preamplifier also provides added bandwidth and improved noise performance.

The filter section of the device consists of a CT multistage filter, a narrowband SC filter, and an additional low-pass CT filter. The first stage is used to provide gain and selectivity while the second stage provides additional selectivity. The narrowband SC filter allows for targeted band-pass or notch filtering of signals while the low-pass CT stage provides additional fine-tune filtering as required. The various filter modules are configured using an internal control logic that is designed to provide maximum flexibility and performance.

The filter can be used for sharpening up signals before further conversion or processing stages, or for suppressing unwanted signals from the input prior to processing. The LTC1062CSW#TRPBF also includes adjustable pole-zero cancellation, allowing for high power signals to be implemented without compromising the band-pass filter\'s linearity. The adjustable pole-zero cancellation feature is also ideal for use in audio signal chain applications.

Overall, the LTC1062CSW#TRPBF is an excellent choice for professional audio signal processing and other active filter applications, particularly where low-noise, low-power performance is desired. The adjustable pole-zero cancellation feature allows for signal optimization, while the hybrid filter architecture provides flexibility and performance. Additionally, the device provides a low-noise preamplifier and driver stage for added signal conditioning.
