查看全系列相关产品产品概述
The MAX5113GTJ+ from Maxim Integrated Products is a 9-channel, 14bit current digital to analogue converter (DAC) with SPI interface in 32 pin TQFN package. The device's output ranges are optimized to bias a high power tunable laser source. Each of the 9 channels provides a current source. Channels 1 and 2 provide 10mA current. An internal multiplexer switch the outputs of each channel to one of four external nodes. Channel 3 provides a selectable current of 2mA or 20mA. Channel 4 provides 90mA. Channel 5 provides 180mA. Channel 6 provides a selectable current of -60mA or +300mA. Channel 7 provides 90mA. Channel 8, 9 provides a selectable current of 15mA or 35mA. Connect DAC outputs in parallel to obtain additional current or to achieve higher resolution. An active-high asynchronous CLR input resets DAC codes to zero independent of the serial interface. It has separate power supply input for driving the interface logic. Typically used at tunable laser diode biasing.
- Supply voltage of 2.6V to 3.3V
- Operating temperature range from -40°C to 105°C
- Low 3V supply
- SPI interface drives the device with clock rates of up to 25MHz
- Integrated multiplexers for outputs 1 and 2
- Increased current or resolution with outputs connected in parallel
- Internal reference
- Over temperature protection
