It is designed to amplify low level signals with minimum noise contribution while operating in the harsh, interference-rich environments of newly deployed digital subscriber units. The device also functions as an out- standing PA driver amplifier in the transmit chain of digital subscriber units where low transmit noise power is a con- cern. The device supports trade-offs between linearity and current drain. The designer has control of these trade-offs with the choice of an external bias resistor. The IC is featured in a standard miniature 8-lead plastic MSOP package. 0.192 + 0.008 0.012 0.006 + 0.003 -A- 0.118 + 0.004 sq. 6° MAX 0° MIN 0.021 + 0.004 0.0256 0.006 + 0.002 0.034 NOTES: 1.
