Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 7:
Full power bandwidth is calculated from the slew rate: may cause permanent damage to the device. Exposure to any Absolute FPBW = SR/(π • V P-P) Maximum Rating condition for extended periods may affect device
Note 8:
Differential gain and phase are measured using a Tektronix reliability and lifetime. TSG120YC/NTSC signal generator and a Tektronix 1780R video
Note 2:
This parameter is guaranteed to meet specifi ed performance measurement set. The resolution of this equipment is better than 0.05% through design and characterization. It is not production tested. and 0.05°. Ten identical amplifi er stages were cascaded giving an effective
Note 3:
As long as output current and junction temperature are kept resolution of better than 0.005% and 0.005°. below the Absolute Maximum Ratings, no damage to the part will occur.
Note 9:
Slew rate is 100% production tested on channel 1. Slew rate of Depending on the supply voltage, a heat sink may be required. channel 2 is guaranteed through design and characterization.
Note 4:
The LT6411C is guaranteed functional over the operating
Note 10:
Since the LT6411 is a feedback amplifi er with low output temperature range of –40°C to 85°C. impedance, a resistive load is not required when driving an ADC.
Note 5:
The LT6411C is guaranteed to meet specifi ed performance from Therefore, typical output power is very small. In order to compare the 0°C to 70°C. The LT6411C is designed, characterized and expected to LT6411 with typical gm amplifi ers that require 50Ω output loading, the meet specifi ed performance from –40°C and 85°C but is not tested or LT6411 output voltage swing driving an ADC is converted to OIP3 and QA sampled at these temperatures. The LT6411I is guaranteed to meet P1dB as if it were driving a 50Ω load. specifi ed performance from –40°C to 85°C.
Note 6:
The two supply voltage settings for power supply rejection are shifted from the typical ±VS points for ease of testing. The fi rst measurement is taken at VCC = 3V, VEE = –1.5V to provide the required 3V headroom for the enable circuitry to function with EN, DGND and all inputs connected to 0V. The second measurement is taken at VCC = 8V, VEE = –4V. 6411f 4
