LT10647FB_15 Datasheet, PDF (3/16 Pages) Linear Technology – Linear Phase, 8th Order Lowpass Filter

LTC1064-7
ELECTRICAL CHARACTERISTICS The ● denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at T_A = 25°C. V_S = ±7.5V, R_L = 10k, f_CUTOFF = 10kHz or 20kHz, f_CLK = 1MHz, TTL or
CMOS level (maximum clock rise and fall time ≤ 1µs) and all gain measurements are referenced to passband gain, unless otherwise
specified. The filter cutoff frequency is abbreviated as f_CUTOFF or f_C.
