EL2280C

EL2180C/EL2280C/EL2480C- EL2180C/EL2280C/EL2480C-Preliminary 250MHz / 3mA Current Mode Feedback Amplifiers Features Single, dual, and quad topologies 3mA supply current (per amplifier) 250MHz -3dB bandwidth 1200V/µs slew rate Tiny package package options (SOT23, LPP) Low cost Single- and dual-supply operation down to ±1.5V 0.05%/0.05° diff. gain/diff. phase into 150Ω General Description The EL2180C/EL2280C/EL2480C are single/dual/quad current-feedback operational amplifiers that achieve a -3dB bandwidth of 250MHz at a gain of +1 while consuming only 3mA of supply current per amplifier. They will operate with dual supplies ranging from ±1.5V to ±6V or from single supplies ranging from +3V to +12V. In spite of their low supply current, the EL2480C and the EL2280C can output 55mA while swinging to ±4V on ±5V supplies. The EL2180C can output 100mA with similar output swings. These attributes make the EL2180C/EL2280C/EL2480C excellent choices for low power and/or low voltage cable driver, HDSL, or RGB applications. For applications where board space is extremely critical, the EL2180C is available in the tiny 5-pin SOT23 package, with a footprint size 28% of an 8-pin SO. The EL2480C is also available in a 24-pin LPP package. All are specified for operation over the full -40°C to +85°C temperature range. Single, dual, and triple versions are also available with the enable function (EL2186C, EL2286C, and EL2386C). Applications Low power/battery appli...
