Like many rail-to-rail input amplifier device. In applications where some protection is needed, but not configurations, it comprises two differential pairs, one N-channel at the expense of reduced output voltage headroom, a low value (M1 to M2) and one P-channel (M3 to M4). These differential resistor in series with the output, as shown in Figure 37, can be pairs are biased by 50 μA current sources, each with a compliance used.

Additional signal current recombination for the output 20Ω AD8532 VOUT stage is achieved using M11 to M14. To achieve rail-to-rail output swings, the AD8531/AD8532/ 01099-037 AD8534 design employs a complementary, common source Figure 37. Output Short-Circuit Protection output stage (M15 to M16). However, the output voltage swing POWER DISSIPATION is directly dependent on the load current because the difference Although the AD8531/AD8532/AD8534 are capable of between the output voltage and the supply is determined by providing load currents to 250 mA, the usable output load the AD8531/AD8532/AD8534’s output transistors on channel current drive capability is limited to the maximum power resistance (see Figure 12 and Figure 13). The output stage also dissipation allowed by the device package used.
