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 Ω).

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.
