The SGM8257-1 is a single, high voltage operational amplifier with high output drive capability. It can operate from 10V to 80V single supply or from ±5V to ±40V dual power supplies. The high voltage SGM8257-1 provides a wide input common mode voltage range and output voltage swing without phase inversion. The device is also capable of delivering a relatively high output current of ±50mA. It offers a gain-bandwidth product of 2.8MHz and can keep unity-gain stable in applications.
The SGM8257-1 includes built-in over-current and over-temperature protections. These conditions are monitored via the Status Flag pin, which is an open-drain output. When either condition occurs, the Status Flag pin goes active, alerting the system to take protective measures.
Additionally, the SGM8257-1 features a disable function. The E/D pin can enable or disable the output stage independently without affecting input signal transmission. The E/D COM pin serves as a common return, simplifying the connection of the E/D pin to low-voltage logic circuits. The disable function helps reduce power consumption and protects the load when the amplifier output is not needed.
The SGM8257-1 is available in a Green SOIC-8 (Exposed Pad) package. It is specified from 0℃ to +70℃ temperature range.
