SCDS475A April 2024 – July 2024 SN4599-Q1
PRODUCTION DATA
Refer to the PDF data sheet for device specific package drawings
The application shown in Figure 8-3 demonstrates how to toggle between the DAC output and GND to control a power amplifier using a single control input. The DAC output is utilized to bias the gate of the power amplifier and can be disconnected from the circuit using the select pin of the switch.
The SN4599-Q1 can operate without any external components except for the supply decoupling capacitors. It is recommended to have a weak pull-down or pull-up resistor so that the input of the select pin is in a known state. All inputs to the switch must fall within the recommend operating conditions of the SN4599-Q1 including signal range and continuous current. For this design with a supply of 5V, the signal range can be 0V to 5V and the maximum continuous current can be 30mA.
