LTC1063 Datasheet - Linear Technology

DESCRIPTION
The LTC1063 is the first monolithic filter providing both clock-tunability, low DC output offset and over 12-bit DC accuracy. The frequency response of the LTC1063 closely approximates a 5th order Butterworth 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, the CMR of the device is 80dB.
