1 / 16 page LT1568 1 1568f The LT ®1568 is an easy-to-use, active-RC filter building block with rail-to-rail inputs and outputs. The internal ca- pacitors of the IC and the GBW product of the internal low noise op amps are trimmed such that consistent and repeat- able filter responses can be achieved. With a single resis- tor value, the LT1568 provides a pair of matched 2-pole Butterworth lowpass filters with unity gain suitable for I/Q channels. By using unequal-valued external resistors, the two 2-pole sections can create different frequency responses or gains. In addition, the two stages may be cascaded to create a single 4-pole filter with a programmable re- sponse. Capable of cutoff frequencies up to 10MHz, the LT1568 is ideal for antialiasing or channel filtering in high speed data communications systems. The LT1568 can also be used as a bandpass filter. The LT1568 features very low noise, supporting signal-to- noise ratios of over 90dB. It also provides single-ended to differential signal conversion for directly driving high speed A/D converters. The LT1568 has a shutdown mode that reduces supply current to approximately 0.5mA on a 5V supply. The LT1568 is available in a narrow 16-lead SSOP package. , LTC and LT are registered trademarks of Linear Technology Corporation. s Up to 10MHz Center Frequency on a Single 3V Supply s Easy to Use—A Single Resistor Value Sets Lowpass Cutoff Frequency (200kHz ≤ ƒC ≤ 5MHz), Unequal Resistor Values Extend Cutoff Frequency Up to 10MHz s Extremely Flexible—Different Resistor Values Allow Lowpass Transfer Functions with or Without Gain (Butterworth, Chebyshev or Custom) s SNR = 92dB ( ƒC = 2MHz, 2VP-P) s THD = –84dB ( ƒC = 2MHz, 1VP-P) s Internal Capacitors Trimmed to ±0.75% s Single 4-Pole Lowpass Filter or Matched Pair of 2-Pole Lowpass Filters s Can be Connected as a Bandpass Filter s Single-Ended or Differential Output s Operates from Single 3V (2.7V Min) to ±5V Supply s Rail-to-Rail Input and Output Voltages Very Low Noise, High Frequency Active RC, Filter Building Block s Replaces Discrete RC Active Filters and LC Filter Modules s Antialiasing/Reconstruction Filters s Dual or I-and-Q Channels (Two Matched 2nd Order Filters in One Package) s Single-Ended to Differential Conversion s Video Signal Processing V+ INVA SA OUTA OUTA GNDA NC V– V+ INVB SB OUTB OUTB GNDB EN V– 1 2 3 4 5 6 7 8 16 15 14 13 12 11 10 9 LT1568 511 Ω 0.1 µF 0.1 µF 511 Ω 511 Ω 511 Ω 511 Ω 1568 TA01 VINA 3V VOUTA VOUTA VINB THE PROPRIETARY ARCHITECTURE ALLOWS FOR A SIMPLE RESISTOR CALCULATION: VOUTB VOUTB 511 Ω R = 128 Ω •; ƒC = CUTOFF FREQUENCY 10MHz ƒC Amplitude and Phase Matched Dual Butterworth 2.5MHz Lowpass Filter with Differential Output.
