VS = ±5V; VCM = VOUT = 0V, unless otherwise noted. (Note 5) ELECTRICAL CHARACTERISTICS Note 1: Absolute maximum ratings are those values beyond which the life of the device may be impaired. Note 2: Inputs are protected by back-to-back diodes and diodes to each supply. If the inputs are taken beyond the supplies or the differential input voltage exceeds 0.7V, the input current must be limited to less than 40mA. 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 LT6202C/LT6202I, LT6203C/LT6203I and LT6204C/LT6204I are guaranteed functional over the temperature range of –40 °C and 85°C. Note 5: The LT6202C/LT6203C/LT6204C are guaranteed to meet specified performance from 0 °C to 70°C. The LT6202C/LT6203C/LT6204C are designed, characterized and expected to meet specified performance from –40 °C to 85°C, but are not tested or QA sampled at these temperatures. The LT6202I/LT6203I/LT6204I are guaranteed to meet specified performance from –40 °C to 85°C. Note 6: Matching parameters are the difference between the two amplifiers A and D and between B and C of the LT6204; between the two amplifiers of the LT6203. CMRR and PSRR match are defined as follows: CMRR and PSRR are measured in µV/V on the identical amplifiers. The difference is calculated between the matching sides in µV/V. The result is converted to dB. Note 7: Minimum supply voltage is guaranteed by power supply rejection ratio test. Note 8: Output voltage swings are measured between the output and power supply rails. Note 9: This parameter is not 100% tested. Note 10: Full-power bandwidth is calculated from the slew rate: FPBW = SR/2 πVP Note 11: Differential gain and phase are measured using a Tektronix TSG120YC/NTSC signal generator and a Tektronix 1780R Video Measurement Set. The resolution of this equipment is 0.1% and 0.1 °. Ten identical amplifier stages were cascaded giving an effective resolution of 0.01% and 0.01 °. |
