CWD-01-V2

Analog Technologies, Inc. CWD-01-V2 CONSTANT CURRENT CW LASER DRIVER Description This laser driver is for driving diode lasers with high stability and high power efficiency. It provides these functions: laser constant current control, laser current monitoring, control loop stability indications, and shut down. It provides a high stability and low noise 2.5V reference voltage which can be used for setting the output current, or for ADCs & DACs. Main features: high efficiency, low noise, high reliability, zero EMI and small package. Part number: Laser current control signal level: Control accuracy: Laser current indication signal level: Indication accuracy: Maximum output current: Current output noise: Laser driver efficiency: Power input DC voltage: Output reference voltage: Operating temperature: Pin Descriptions Pin 1 SDNG, shut down control, digital input. Negative logic, at the internal chip control input: >1.4V = enable, 1V, the control loop is working properly. When this pin is low,
