2.5MHz 4-, 8-, 10- and 12-Channel Rail-to-
Rail Buffers
The EL5127, EL5227, EL5327, and EL5427 are low power,
high voltage rail-to-rail input/output buffers designed for use
in reference voltage buffering applications in small LCD
displays. They are available in quad (EL5127), octal
(EL5227), 10-Channel (EL5327), and 12-Channel (EL5427)
topologies. All buffers feature a -3dB bandwidth of 2.5MHz
and operate from just 133µA per buffer. This family also
features a continuous output drive capability of 30mA (sink
and source).
The quad channel EL5127 is available in the 10 Ld MSOP
package. The 8-Channel EL5227 is available in both the
20 Ld TSSOP and 24 Ld QFN packages, the 10-Channel
EL5327 in the 24 Ld TSSOP and 24 Ld QFN packages, and
the 12-Channel EL5427 in the 28 Ld TSSOP and 32 Ld QFN
packages. All buffers are specified for operation over the full
-40°C to +85°C temperature range.
Features
• 2.5MHz -3dB bandwidth
• Supply voltage = 4.5V to 16.5V
• Low supply current (per buffer) = 133µA
• High slew rate = 2.2V/µs
• Rail-to-rail input/output swing
• Ultra-small packages
• Pb-free plus anneal available (RoHS compliant)
Applications
• TFT-LCD drive circuits
• Electronic games
• Touch-screen displays

Applications Information
Product Description
The EL5127, EL5227, EL5327, and EL5427 unity gain
buffers are fabricated using a high voltage CMOS process. It
exhibits rail-to-rail input and output capability and has low
power consumption (120µA per buffer). These features
make the EL5127, EL5227, EL5327, and EL5427 ideal for a
wide range of general-purpose applications. When driving a
load of 10k and 12pF, the EL5127, EL5227, EL5327, and
EL5427 have a -3dB bandwidth of 2.5MHz and exhibits
2.2V/µs slew rate.
Operating Voltage, Input, and Output
The EL5127, EL5227, EL5327, and EL5427 are specified
with a single nominal supply voltage from 5V to 15V or a split
supply with its total range from 5V to 15V. Correct operation
is guaranteed for a supply range of 4.5V to 16.5V. Most
EL5127, EL5227, EL5327, and EL5427 specifications are
stable over both the full supply range and operating
temperatures of -40°C to +85°C. Parameter variations with
operating voltage and/or temperature are shown in the
typical performance curves.
The output swings of the EL5127, EL5227, EL5327, and
EL5427 typically extend to within 80mV of positive and
negative supply rails with load currents of 5mA. Decreasing
load currents will extend the output voltage range even
closer to the supply rails. Figure 22 shows the input and
output waveforms for the device. Operation is from ±5V
supply with a 10k load connected to GND. The input is a
10VP-P sinusoid. The output voltage is approximately
9.985VP-P.
