EL5220C, EL5420C
12MHz Rail-to-Rail Input-Output Op Amps
Features
General Description
• 12MHz -3dB bandwidth
• Supply voltage = 4.5V to 16.5V
• Low supply current (per amplifier)
= 500µA
• High slew rate = 10V/µs
• Unity-gain stable
• Beyond the rails input capability
• Rail-to-rail output swing
• Ultra-small package
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 sup-
plies 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 sup-
ply 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.
Applications
• TFT-LCD drive circuits
• Electronics notebooks
• Electronics games
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.
