ANALOG DEVICES LTC1065CSW#PBF Analogue Filter, Bessel, Lowpass, 5th, 1, 2.375 V, 8 V, WSOIC

LTC®1065 is the first monolithic linear phase lowpass filter providing both clock-tunability with low DC output offset and over 12-bit DC accuracy. Its frequency response is closely approximates a 5th order Bessel polynomial. With appropriate PCB layout techniques the output DC offset is typically 1mV and is constant over a wide range of clock frequencies. With ±5V supplies and ±4V input voltage range, this CMR of the device is typically 80dB. Its cut-off frequency is controlled either by an internal or external clock. The clock-to-cut-off frequency ratio is 100:1. This on-board clock is nearly power supply independent and it is programmed via an external RC. Its 50µVRMS clock feedthrough of the device is considerably lower than other existing monolithic filters. Typical applications are audio, strain gauge amplifiers, anti-aliasing filters, low level filtering, digital voltmeters, smoothing filters, reconstruction filters.
