6 / 16 page LT1568 6 1568f SYMBOL PARAMETER CONDITIONS MIN TYP MAX UNITS Filter Gain Mismatch fC = 1MHz, fIN = fC q –0.3 ±0.10 0.3 dB (VOUTA – VOUTA)– (VOUTB – VOUTB) fC = 10MHz, fIN = fC q –0.4 ±0.15 0.4 dB Wideband Output Noise fC = 1MHz, RFIL = 1.28k, BW = 2MHz 36 µVRMS fC = 10MHz, RFIL = 128Ω, BW = 20MHz 88 µVRMS THD Total Harmonic Distortion fC = 1MHz, RFIL = 1.28k, – 84 dB fIN = 200kHz, VIN = 1VP-P fC = 10MHz, RFIL = 128Ω,– 69 dB fIN = 2MHz, VIN = 1VP-P Note 1: Absolute Maximum Ratings are those values beyond which the life of the device may be impaired. Note 2: The inputs of each op amp are protected by back-to-back diodes. If either differential input voltage exceeds 1.4V, the input current should be limited to less than 10mA. Note 3: A heat sink may be required to keep the junction temperature below the absolute maximum rating when the output is shorted indefinitely. Note 4: The inverter bandwidth is measured with the SA or SB output floating, and is defined as the frequency at which the phase shift from OUTA (OUTB) to OUTA (OUTB) drops from 180 ° to 135°. Note 5: Measured with the SA or SB output connected in the filter application circuit as shown in the Block Diagram. Note 6: The common mode input voltage range is measured by shorting the filter input to the common mode reference (GNDA or GNDB) and applying a DC input voltage to search for the common mode voltage range that creates a ±2mV (VS = 3V) or ±5mV (VS = ±5V) change in the (OUTA or OUTB) voltage (measured with respect to GNDA or GNDB). Note 7: The minimum cutoff frequency of the LT1568 is arbitrarily listed as 200kHz. The limit is arrived at by setting the maximum resistor value limit at 6.4k. Due to input bias current, the output DC offset through a single section can be as high as 25mV with resistors this large. The LT1568 can be used with even larger resistors if the large offset voltages can be tolerated. For cutoff frequencies below 200kHz, refer to the LTC1563-2, LTC1563-3. Note 8: With equal-sized resistors, the differential DC gain through either a single section or cascaded sections is 6dB. Note 9: The LT1568C is guaranteed to meet specified performance from 0 °C to 70°C. The LT1568C is designed, characterized and expected to meet specified performance from –40 °C to 85°C but is not tested or QA sampled at these temperatures. The LT1568I is guaranteed to meet specified performance from –40 °C to 85°C. Specifications are for the differential output (OUTA – OUTA or OUTB – OUTB) of a single 2nd order section (A or B), gain = –2, RFIL = R11 = R21 = R31 = R12 = R22 = R32. All voltages are with respect to VGND = VGNDA = VGNDB. The q denotes the specifications which apply over the full operating temperature range, otherwise specifications and typical values are at TA = 25°C. VS = single 5V, EN pin to logic “low,” RLDIFF = 800Ω connected to midsupply, unless otherwise noted. FILTER ELECTRICAL CHARACTERISTICS |
