ELECTRICAL CHARACTERISTICS The q denotes the specifications which apply over the full operating

temperature range, otherwise specifications are at TA = 25°C. VS = ±5V, RL = 150Ω, CL = 1.5pF, VEN = 0.4V, VAGND, VDGND = 0V.

UNITS

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 LT6553C is guaranteed functional over the operating

temperature range of –40

°C to 85°C.

Note 5: The LT6553C is guaranteed to meet specified performance from

°C to 70°C. The LT6553C 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 LT6553I 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 data 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: Full power bandwidth is calculated from the slew rate:

FPBW = 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 0.1%

and 0.1

°. Nine identical amplifier stages were cascaded giving an effective

resolution of better than 0.011% and 0.011

°.
