DescriptionThe EL2070 is a wide bandwidth, fast settling monolithic amplifier incorporating a disable/enable feature.
Built using an advanced complementary bipolar process, this amplifier uses current-mode feedback to achieve more bandwidth at a given gain than conventional operational amplifiers. Designed for closed-loop gains of ±1 to ±8, the EL2070 has a 200MHz -3dB bandwidth (AV = +2), and 12ns settling to 0.05% while consuming only 15mA of supply current. Furthermore, the fast disable/enable times of 200ns/100ns allow rapid analog multiplexing.
The EL2070 is an obvious high-performance solution for video distribution and line-driving applications, especially when its disable feature can be used for fast analog multiplexing. Furthermore, the low 15mA supply current, and the very low 5mA of supply current when disabled suggest use in systems where power is critical. With differential gain/phase of 0.02%/0.01°, guaranteed video specifications, and a minimum 50mA output drive, performance in these areas is assured.
The EL2070's settling to 0.05% in 12ns, low distortion, and ability to drive capacitive loads make it an ideal flash A/D driver. The wide 200MHz bandwidth and extremely linear phase allow unmatched signal fidelity. D/A systems can also benefit from the EL2070, especially if linearity and drive levels are important.
