PRODUCT DESCRIPTION
The ADEL2020 is an improved second source to the EL2020.
This op amp improves on all the key dynamic specifications
while offering lower power and lower cost. The ADEL2020 of-
fers 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

Fine-Scale Gain (Normalized) vs. Frequency for Various
Supply Voltages. RF = 750 Ω, Gain = +2
than the competition while offering higher output drive. Impor-
tant 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 guaran-
teed 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.
