DESCRIPTION

The high voltage operational amplifier provides up to 1500V

input voltage and 100mA load current without any additional

circuit. The input port has over voltage protection and the

output port has short-circuit protection. When the product gets

overheated, the temperature sensing circuit will shut down by

itself to prevent the amplifier from being damaged by the

excessive heat.

The high voltage operational amplifier has a low noise, high

precision and wide output swing, there is no reverse phase

problem encountered in the same kind of products. The output

can be stopped by the on/off (E/D) pin, which is in the loop

pin and can be connected with the low voltage logic circuit,

thus realizing non-interference input signal. It not only saves

power, but also protects the load.

External compensation provides flexibility in choosing

bandwidth and slew rate for the application. The power supply

is independent and takes up very little space, so a high density

board can be used.

With an appropriate current limiting resistor, the internal

power consumption can be selected under any load. The

product is suitable for a wide range of power supply voltage

and achieves good power supply voltage control. The output

stage can be biased into a linear operational amplifier.

A class H amplifier circuit includes a Buck converter and a

charge pump, and the latter is used to generate voltages for

powering an output driver in turn. A feedback path controls

the loop. The circuit is particularly suitable as a high

efficiency circuit for driving headphones or loudspeakers.

The pin names and locations are shown in Figure 2. The pin

function description is shown in Table 1.
