LTC1059CS#TRPBF is an integrated low-power active filter. Due to its high performance, wide operating temperature range and availability in standard small-size packages, it is widely used in various applications.

Functionally, LTC1059CS#TRPBF is a fourth-order low-pass filter with a Butterworth response. In addition to its fourth-order elliptic filter architecture, the device also features programmable output drive and bandwidth limiting. This allows designers to tailor the filter performance to the specific application.

The main application of LTC1059CS#TRPBF is in industrial and automotive applications, where it is used to help reduce out-of-band noise and limit the bandwidth of high-frequency signals. The device can also be used in telephony applications to reduce the probability of false triggering due to line glitches. Its low power consumption and ability to operate in a wide temperature range make it an ideal solution for remote applications which need to maintain reliable performance over a wide temperature range.

In terms of working principle, LTC1059CS#TRPBF features a low-offset, low-power operational amplifier. An external resistor network sets the filter cutoff frequency. The device also features a 4-bit digital-to-analog converter (DAC) which sets the amplification of the output signal. The DAC can be controlled by an I2C serial interface, which enables digital-domain control of the device.

To ensure reliable performance over a wide temperature range, LTC1059CS#TRPBF includes a tiny on-chip temperature sensor which continuously monitors the ambient temperature and adjusts the device\'s parameters accordingly. This feature makes it well-suited for remote applications where temperature range is a determining factor.

In conclusion, the LTC1059CS#TRPBF integrated active filter is an ideal solution for industrial and automotive applications which need to reduce out-of-band noise and maintain reliable performance over a wide temperature range. Its low-power, low-offset operational amplifier and 4-bit DAC allow digital-domain control, while its on-chip temperature sensor ensures reliable performance over a wide temperature range.
