Product Specification

AD5005 Temperature Controller and Laser Diode Driver GENERAL DESCRIPTION
The AD5005 is a high precision laser diode and temperature controller series coming in several models to work with all low power laser diodes. Based on its low noise current driver and high efficient temperature controller, it best fits your applications with high performance.

The laser current driver feeds high stable current with noise below75μA and incorporates all essential protection strategies to laser diode. The driver offers excellent current stability in constant current mode or power stability in constant power mode.Furthurmore,it supports external modulation of sinewave with small signal 3dB bandwidth from DC to 500KHz

The temperature controller is built based on reliable and precise circuitry. It is ideal for high performance applications like wavelength locking. By the help of adjustable Proportional Gain(P) and Integrator Time Constant(I) ,it achieves temperature stability better than 0.005°C.Any type of temperature sensors are compatible with AD5005.

AD5005 supports local and remote operation. By a USB2.0 interface, users can operate it via PC conveniently.
