DESCRIPTION
The SGM41290 is a highly bias and monitoring management circuit for silicon optical control applications. There are twelve channels of 12-bit programmable current/voltage output DACs with a maximum output current of 40mA and four channels of 12-bit 300mA high-current output DACs. The IC also has twelve MULTI_IO pins (MULTI_IOx) to monitor the current or DAC output signal. The functions of the twelve pins are configurable respectively through the I2C interface or SPI.
The SGM41290 is available in a Green WLCSP-3.98×3.89-56B package. It operates over an ambient temperature range of -40℃ to +105℃.
