Low Noise 3
This slide shows how this new device performs from a Gain/Phase Margin and Load capacity perspective. The left side of this graph shows gain/phase measurements completed for this device. Using the same product A and product B comparison from the previous slides, shows that optimizations used to reduce the noise of product A result in about a 24 degree phase margin whereas using ROHM’s LMR1802G shows lower noise and better stability with a 68 degree phase margin. Similarly, the load capacity tolerance of the LMR1802G is also capable of 500 pF, 5x of product A (100 pF) and double that of product B (250 pF). The CMOS technology along with some of ROHM’s patented circuit optimization techniques allow for the engineer to reach the low noise thresholds for this OpAmp while maintaining good stability and load performance.
