Product Details
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 high 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 plastic DIP and SOIC packages.
