This op amp improves on all the key dynamic specifications while offering lower power and lower cost.
The ADEL2020 offers 50% more bandwidth and gain flatness of 0.
1 dB to beyond 25 MHz.
In addition, differential gain and phase are less than 0.
05% and 0.
05° while driving one back terminated cable (150 Ω).
The ADEL2020 offers other significant improvements.
The most important of these is lower power supply current, 33% less +0.
1 0 NORMALIZED GAIN – dB than the competition while offering higher output drive.
Important specs like voltage noise and offset voltage are less than half of those for the EL2020.
The ADEL2020 also features an improved disable feature.
The disable time (to high output impedance) is 100 ns with guaranteed break before make.
Finally the ADEL2020 is offered in the industrial temperature range of –40°C to +85°C in both plastic DIP and SOIC package.
