Note 1:
Absolute Maximum Ratings are those values beyond which the life
Note 6:
The two supply voltage settings for power supply rejection are of a device may be impaired. shifted from the typical ±VS points for ease of testing. The first
Note 2:
This parameter is guaranteed to meet specified performance measurement is taken at V+ = 3V, V– = –1.5V to provide the required 3V through design and characterization. It is not production tested. headroom for the enable circuitry to function with EN, DGND, AGND and
Note 3:
As long as output current and junction temperature are kept below all inputs connected to 0V. The second measurement is taken at V+ = 8V, the Absolute Maximum Ratings, no damage to the part will occur. V– = –4V. Depending on the supply voltage, a heat sink may be required.
Note 7:
Large signal bandwidth is calculated from the slew rate:
Note 4:
The LT6554C is guaranteed functional over the operating LSBW = SR/(π • VP-P) temperature range of –40°C to 85°C.
Note 8:
Differential gain and phase are measured using a Tektronix
Note 5:
The LT6554C is guaranteed to meet specified performance from TSG120YC/NTSC signal generator and a Tektronix 1780R video 0°C to 70°C. The LT6554C is designed, characterized and expected to measurement set. The resolution of this equipment is better than 0.05% meet specified performance from –40°C and 85°C but is not tested or QA and 0.05°. Nine identical amplifier stages were cascaded giving an sampled at these temperatures. The LT6554I is guaranteed to meet effective resolution of better than 0.0056% and 0.0056°. specified performance from –40°C to 85°C.
Note 9:
Slew rate is 100% production tested on the G channel. Slew rate of the R and B channels is guaranteed through design and characterization. 6554fa 3
