The EL5421 is a quad, low power, high voltage rail-to-rail input-output buffer. Operating on supplies ranging from 5V to 15V, while consuming only 500µA per channel, the EL5421 has a bandwidth of 12MHz (-3dB). The EL5421 also provides rail-to-rail input and output ability, giving the maximum dynamic range at any supply voltage.
The EL5421 also features fast slewing and settling times, as well as a high output drive capability of 30mA (sink and source). These features make the EL5421 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 EL5421 is available in a space saving 10 Ld MSOP package and operates over a temperature range of -40°C to +85°C.
