... Cauer response with lower noise and lower delay nonlinearity than the Cauer response. The stopband attenuation at 2.5 × f 50kHz can be achieved. The LTC1064-4 features low noise and low harmonic distortion even when input voltages applied. The LTC1064-4 overall performance competes with equivalent multiple op amp active realizations. The LTC1064-4 is pin compatible with the LTC1064-1, LTC1064-2 and LTC1064-3 ...

... Pin 10 should be tied For an f 100:1, Pin 10 should be tied to V midsupplies (i.e. ground), the filter response is neither Cauer nor transitional. Table 6 illustrates this response. Bypassing Pin 10 with a 0.1µF capacitor reduces the already small clock feedthrough. LTC1064-4 /f ratio of 50:1, CLK C /f ratio of CLK – ...
