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 10kΩ and 12pF, the EL5127, EL5227, EL5327, and
EL5427 have a -3dB bandwidth of 2.5MHz and exhibits
2.2V/µs slew rate.
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 10kΩ load connected to GND. The input is a
10V
P-P
sinusoid. The output voltage is approximately
9.985V
P-P
.
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
