General Description
The EL2030 is a very fast wide bandwidth amplifier optimized for gains between b 10 and a 10 Built using the Elantec monolithic Complementary Bipolar process this amplifier uses current mode feedback to achieve more bandwidth at a given gain than a conventional voltage feedback operational amplifier Due to its wide operating supply range ( g 15V) and extremely high slew rate of 2000 V ms the EL2030 drives g 10V into 200X at a frequency of 30 MHz while achieving 110 MHz of small signal bandwidth at AV e a 2 This bandwidth is still 95 MHz for a gain of a 10 On g 5V supplies the amplifier maintains a 90 MHz bandwidth for AV e a 2 When used as a unity gain buffer the EL2030 has a 120 MHz bandwidth with the gain precision and low distortion of closed loop buffers The EL2030 features extremely low differential gain and phase a low noise topology that reduces noise by a factor of 2 over competing amplifiers and settling time of 40 ns to 0 25% for a 10V step The output is short circuit protected In addition datasheet limits are guaranteed for g 5V and g 15V supplies Elantec’s products and facilities comply with applicable quality specifications See Elantec document QRA-1 Processing Monolithic Integrated Circuits
