General Description

The EL5420C and EL5220C are low power, high voltage, rail-to-rail input-output amplifiers. The EL5220C contains two amplifiers in one package, and the EL5420C contains four amplifiers. Operating on supplies ranging from 5V to 15V, while consuming only 500µA per amplifier, the EL5420C and EL5220C have a bandwidth of 12MHz -- (-3dB). They also provide common mode input ability beyond the supply rails, as well as rail-to-rail output capability. This enables these amplifiers to offer maximum dynamic range at any supply voltage.

The EL5420C and EL5220C also feature fast slewing and settling times, as well as a high output drive capability of 30mA (sink and source). These features make these amplifiers ideal for use as voltage reference buffers in Thin Film Transistor Liquid Crystal Displays (TFT-LCD). Other applications include battery power, portable devices, and anywhere low power consumption is important.

The EL5420C is available in a space-saving 14-pin TSSOP package, the industry-standard 14-pin SO package, as well as a 16-pin LPP package. The EL5220C is available in the 8-pin MSOP package. Both feature a standard operational amplifier pin out. These amplifiers are specified for operation over the full -40°C to +85°C temperature range.
