The ensured specifications apply only for the test conditions listed. Some performance characteristics may change when the device is not operated under the listed test conditions. (2) Typical specifications are specified at +25°C and represent the most likely parametric norm. (3) The supply current specified is the quiescent current for VCC = 5V and with RL = ∞. Load resistors are not required and are not used in the test circuit, therefore all the supply current is used by the pre-amp. (4) Linearity Error is the maximum variation in step height of a 16 step staircase input signal waveform with a 0.7 VP-P level at the input. All 16 steps equal, with each at least 100 ns in duration. (5) dt/dVCC = 200*(t5.5V–t4.5V)/((t5.5V + t4.5V)) %/V, where: t5.5V is the rise or fall time at VCC = 5.5V, and t4.5V is the rise or fall time at VCC = 4.5V. (6) Input from signal generator: tr, tf < 1 ns. (7) Measure output levels of the other two undriven amplifiers relative to the driven amplifier to determine channel separation. Terminate the undriven amplifier inputs to simulate generator loading. Repeat test at fIN = 10 MHz for VSEP 10 MHz. (8) ΔAV track is a measure of the ability of any two amplifiers to track each other and quantifies the matching of the three gain stages. It is the difference in gain change between any two amplifiers with the contrast set to AV 50% and measured relative to the AV MAX condition. For example, at AV MAX the three amplifiers' gains might be 12.1 dB, 11.9 dB, and 11.8 dB and change to 2.2 dB, 1.9 dB and 1.7 dB respectively for contrast set to AV 50%. This yields a typical gain change of 10.0 dB with a tracking change of ±0.2 dB. (9) The ABL input provides smooth decrease in gain over the operational range of 0 dB to −5 dB: ΔAABL = AV MAX – AV (VABL = VABL MIN GAIN). Beyond −5 dB the gain characteristics, linearity and pulse response may depart from normal values. 4 Submit Documentation Feedback Copyright © 2005–2013, Texas Instruments Incorporated Product Folder Links: LM1229 |
