LTC1164-8 Ultraselective, Low Power 8th Order Elliptic Bandpass Filter with Adjustable Gain FEATURES DESCRIPTION Ultraselectivity The LTC®1164-8 is a monolithic ultraselective, 8th order, (50dB Attenuation at ±4% of Center Frequency) elliptic bandpass filter. The passband of the LTC1164-8 is Adjustable Passband Gain tuned with an external clock and the clock-to-center fre- Noise Independent of Gain quency ratio is 100:1. The –3dB pass bandwidth is typi- Filter Noise: 270µVRMS, VS = Single 5V Supply cally 1% of the filter center frequency. The stopband Clock-Tunable (Center Frequency = fCLK/100) attenuation of the LTC1164-8 is greater than 50dB. The Center Frequencies up to 5kHz, VS = ±5V lower and upper stopband frequencies are less than (Typical ISUPPLY = 3.2mA) 0.96 • center
