Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: This parameter is guaranteed to meet specified performance
through design and characterization. It is not production tested.
Note 3: As long as output current and junction temperature are kept below
the Absolute Maximum Ratings, no damage to the part will occur.
Depending on the supply voltage, a heat sink may be required.
Note 4: The LT6554C is guaranteed functional over the operating
temperature range of –40°C to 85°C.
Note 5: The LT6554C is guaranteed to meet specified performance from
0°C to 70°C. The LT6554C is designed, characterized and expected to
meet specified performance from –40°C and 85°C but is not tested or QA
sampled at these temperatures. The LT6554I is guaranteed to meet
specified 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 first
measurement is taken at V+ = 3V, V= –1.5V to provide the required 3V
headroom for the enable circuitry to function with EN, DGND, AGND and
all inputs connected to 0V. The second measurement is taken at V+ = 8V,
V= –4V.
Note 7: Large signal bandwidth is calculated from the slew rate:
LSBW = SR/(π VP-P)
Note 8: 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 better than 0.05%
and 0.05°. Nine identical amplifier stages were cascaded giving an
effective resolution of better than 0.0056% and 0.0056°.
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.
