GENERAL 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
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
).

The ADEL2020 offers other significant improvements. The
most important is lower power supply current (33% less than the
competition) with higher output drive. Important specifications
like voltage noise and offset voltage are less than half of those
for the EL2020. The ADEL2020 also provides an improved
disable feature. The disable time (to high output impedance) is
100 ns with guaranteed break before make. The ADEL2020 is
offered for the industrial temperature range of –40
°C to +85°C
and comes in both PDIP and SOIC packages.
