BLOCK DESCRIPTIONS
PA Block
The Power Amplifier (PA) block consists of a high slew rate, high-voltage, and high-current operational amplifier.
The PA is configured with an inverting gain of 6.5 V/V, has a low-pass filter response, and maintains excellent
linearity and low distortion. The PA is specified to operate from 7 V to 24 V and can deliver up to ±1.5 A of
continuous output current over the specified junction temperature range of –40°C to +125°C. Figure 25 illustrates
the PA block.
Figure 25. PA Block Equivalent Circuit
Connecting the PA in a typical PLC application requires only two additional components: an ac coupling
capacitor, CIN, and the current limit programming resistor, RSET. Figure 26 shows the typical connections to the
PA block.
