A438S10TAC

The A438S10TAC is a transimpedance amplifier with two stage feedback configurations. Any change in input current will be reflected as change in output voltage swing. A resistor in series with the input will change the A438S10TAC into a voltage amplifier. The output is emitter follower with load(capacitive) driven capability.

The A438S10TAC is a high voltage, low quiescent current MOSFET operational amplifier designed as a low cost solution for driving continuous output currents up to 8A and pulse currents up to 14A. The safe operating area (SOA) has no second break- down limitations and can be observed for all type loads by choosing an appropriate current limiting resistor. The MOSFET output stage is biased AB for linear operation. External com- pensation provides flexibility in choosing bandwidth and slew rate for the application. APEXs Power SIP package uses a minimum of board space allowing for high density circuit boards.

In order to conserve power, the OTG Supplement allows an A-device to leave VBUS turned off when the bus is not being used. Then, when the B-device wants to use the bus, A438S10TAC follows the SRP pulsing protocol to request that the A-device supply power to VBUS. In the configuration in Figure 1, the OTG Host would be considered the A-device, and the USB20H04 Hub would be considered the B-device.The information presented in this document does not form part of any quotation or contract, is believed to be accurate and reliable and may be changed without notice.
