PRODUCTION DATA
Refer to the PDF data sheet for device specific package drawings
The application shown in Figure 8-1 demonstrates how to use a single control input and toggle between gain settings of -1 and +1. If switching between inverting and unity gain is not required, then the SN4599-Q1 can be utilized in the feedback path to select different feedback resistors and provide scalable gain settings for configurable signal conditioning.
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 3.3V, the signal range can be 0V to 3.3V and the maximum continuous current can be 30mA.
