EL5127C, EL5227C, EL5327C, EL5427C - Product Brief
2.5MHz 4-, 8-, 10- & 12-Channel Rail-to-Rail Buffers
Features
General Description
• 2.5MHz -3dB bandwidth
• Supply voltage = 4.5V to 16.5V
The EL5127C, EL5227C, EL5327C, and EL5427C are low power,
high voltage rail-to-rail input/output buffers designed for use in refer-
ence voltage buffering applications in small LCD displays. They are
available in quad (EL5127C), octal (EL5227C), 10-channel
(EL5327C), and 12-channel (EL5427C) topologies. All buffers feature
a -3dB bandwidth of 2.5MHz and operate from just 120µA per buffer.
This family also features a continuous output drive capability of 30mA
(sink and source).
• Low supply current (per buffer) =
120µA
• High slew rate = 1.5V/µs
• Rail-to-rail input/output swing
• Ultra-small packages
Applications
The quad channel EL5127C is available in the 10-pin MSOP package.
The 8-channel EL5227C is available in both the 20-pin TSSOP and
24-pin LPP packages, the 10-channel EL5327C in the 24-pin TSSOP
and 24-pin LPP packages, and the 12-channel EL5427C in the 28-pin
TSSOP and 32-pin LPP packages. All buffers are specified for opera-
tion over the full -40°C to +85°C temperature range.
• TFT-LCD drive circuits
• Electronic games
• Touch-screen displays
• Personal communication devices
• Personal digital assistants (PDA)
• Portable instrumentation
