LTC6603CUF#PBF

LTC6603CUF#PBF is a low power and high precision active filter designed by Linear Test (LT). It is categorized as an interface filter, activelyrounded by the voltage-controlled resistor (VCR) and charge amplifier, which can provide high linearity and better performance than passive filters.

The operating voltage of LTC6603CUF#PBF ranges from 4V to 16V; the maximum working current is 3mA, so it supports low power consumption. The bandwidth of the filter is 250KHz, and it features 0.01dB passband ripple, so it is highly effective for low-frequency filtering applications.The frequency characteristic is adjustable from 0.25Hz to 250KHz according to the user\'s specific requirements. Other features of this part include better than 78dB attenuation, 0.1/% linearity, high gain (>100V/V), and low input offset voltage (1.2mV max).

In addition, LTC6603CUF#PBF also offers many protection functions, including overload protection, thermal shutdown protection, overvoltage protection, undervoltage lockout, open-drain driver, dead time protections, as well as a shutdown pin. These features make LTC6603CUF#PBF suitable for many industrial applications such as signal filtering, signal amplification, and noise cancellation. Besides, it can be used for other applications, including powerline EMI filters, control circuit noise cancellation, and anti-aliasing filters.

The working principle of LTC6603CUF#PBF is straightforward. It consists of two simultaneous linearization loops: one for the resistor, based on the input signal, and one for the charge amplifier, compensating for the charge-transfer variation. The resistor loop constantly adjusts the resistance to ensure the most linear signal transfer. The charge amplifier loop adjusts the level of signal output voltage to provide a more stable instantaneous voltage. In this way, the signal distortion can be reduced and a more precise signal is obtained.

In conclusion, LTC6603CUF#PBF is a highly efficient and cost-effective active filter solution for high-precision applications. It features low current consumption, wide bandwidth, high linearity, and high gain, which make it ideal for signal filtering and noise reduction. Thanks to its multiple protection functions, it is also reliable and safe in a variety of industrial applications.
