DESCRIPTION

The DRV1101 is fixed gain differential line driver designed for very low distortion operation when driv- ing DSL line transformers. It is designed for use as the upstream line driver for ADSL G.Lite, and as both upstream and downstream line drivers in CAP sys- tems. Operating on a single 5V supply, the DRV1101 can supply up to 230mA peak output current. The output voltage can swing up to 9.5Vp-p on a single 5V supply. In ADSL G.Lite applications, DRV1101 can supply up to 10dBm average line power with a crest factor of 5.3 for a peak line power delivered of approximately 25dBm. It is packaged in a 8-lead SOIC.

(4) Output common-mode voltage follows input common-mode voltage; therefore, if input VCM = VDD /2, then output VCM = VDD /2. (5) THD = 1%. SPECIFICATIONS Typical at 25°C, VCM = VDD /2, VDD = +5.0V, unless otherwise specified.

ELECTROSTATIC DISCHARGE SENSITIVITY This integrated circuit can be damaged by ESD. Burr-Brown recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
