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.

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 10kΩ load connected to GND. The input is a

10VP-P sinusoid. The output voltage is approximately

9.985VP-P.
