The The ADEL2020 is an improved second source to the EL2020. most important is lower power supply current (33% less than the This op amp improves on all the key dynamic specifications competition) with higher output drive. Important specifications while offering lower power and lower cost. The ADEL2020 like voltage noise and offset voltage are less than half of those offers 50% more bandwidth and gain flatness of 0.1 dB to for the EL2020. The ADEL2020 also provides an improved beyond 25 MHz. In addition, differential gain and phase are disable feature. The disable time (to high output impedance) is less than 0.05% and 0.05 while driving one back terminated 100 ns with guaranteed break before make. The ADEL2020 is cable (150 ). offered for the industrial temperature range of 40C to +85C and comes in both PDIP and SOIC packages. +0.1 R = 150 L 0.10 0.20 GAIN = +2 0 15V R = 750 0.09 F 0.18 R = 150 L 0.1 0.08 f = 3.58MHz 0.16 C 5V 100 IRE 0.07 MODULATED RAMP 0.14 0.06 0.12 +0.1 0.05 0.10 R = 1k L 0 0.04 0.08 15V GAIN PHASE 0.1 0.03 0.06 5V 0.02 0.04 0.01 0.02 100k 1M 10M 100M 0 0 516789 10 11 12 13 145 FREQUENCY Hz SUPPLY VOLTAGE V Figure 1.
