CWD-01-V2-D is one of constant current laser diode drivers in ATI. This laser driver is designed for driving diode lasers with high efficiency and constant output current of maximum 2A. This laser diode driver not only comes with high efficiency, but also low noise, zero EMI, and high stability. This laser driver provides the following functions: laser constant current control, laser current monitoring, over current and thermal protection, laser current control indication, laser diode status ind...(more)
LDA1-CP2 is similar with LDA1-CP1, the former is designed for driving N type diode lasers and the latter is for driving P type diode lasers. We are focusing on the first LDA1-CP2 laser driver. This laser diode driver comes with constant current and constant power. The pulse width modulation output stage can achieve more than 90% high power efficiency, so there is no need for any heat sinks. Two independent input voltages can be used to set the output current and the laser power linearly, and two...(more)
LDA1-CP1-D is a dual mode laser diode driver that is designed for driving P type diode lasers. This laser driver comes with well controlled and monitored driving current and output laser power. Two versions of laser drivers are available, LDA1-CP1-D-SNI and the LDA1-CP1-D-SNO, the former refers that external signal synchronizes the signal of the chip, while the latter is that external signal synchronizes the signal of the chip. This laser driver has multiple features, such as high efficiency 90%...(more)
This noise measurement amplifier, ATNMA2, is designed for testing ultra low noises such as nanovolt or microvolt noises that cannot be detected by oscilloscopes. When it detects the noise signals, the noise measurement amplifier amplifies the noise to magnifications, 3,000, 10,000, 30,000, 100,000, 300,000, 1,000,000, 3,000,000, according to different requirements. There are three noise measurement bandwidths: 0.1Hz ~ 10Hz, 0.1Hz ~ 1kHz, 0.1Hz ~ 100kHz. The amplifier comes with a built-in rechar...(more)
For many electronic applications, varying a resistance is necessary when tuning analog electronic circuits. This product, ATRDB12, is an adjustable resistor decade box with knobs for dialing. This resistor decade box comes with a wide adjustable range, from 0.36 to 10M, with a total of eight decades. This decade box has many other features. The resolution is very high 0.1, and the accuracy is also high 1%. Residual resistance is 0.360.01Ω. The maximum power is 0.2W. The operating temperature r...(more)
In the previous two articles, NTC thermistor series ATH10KBL2A and ATH10KL2B have been introduced already. In this article, we will focus on ATH10KL2C series NTC thermistors. This NTC thermistor is also packaged in a small ring lug for easy mounting. Inside the ring lug, there is a thermistor head, ATH10K1R25, which is also in ATH10KL2B NTC thermistors. Therefore, the three thermistors have the same characteristics. The length of the ring lug of ATH10KL2C series thermistors is 11.2mm, and the wi...(more)
ATH10KL2B series NTC thermistor is a thermistor assembly with a ring lug outside a glass encapsulated thermistor head. This series NTC thermistors have three versions, namely, ATH10KL2B, ATH10KL2BT70 and ATH10KL2BT70S. The first one is the basic version. The latter two versions are the upgraded ones. ATH10KL2BT70 comes with two lead wires with plastic tubing, and ATH10KL2BT70S has it sealed between the plastic tubing and the thermistor head. Sealed thermistors can be used in applications with li...(more)
This thermistor ATH10KBL2A is a replacement for ATH10KL2A. ATH10KBL2A series NTC thermistors consist of three versions, ATH10KBL2A, ATH10KBL2AT65 and ATH10KBL2AT65S. The latter two thermistors are based on ATH10KBL2A, with more features. ATH10KBL2A has two bare copper coated lead wires, and ATH10KBL2AT65 has the two lead wires covered with high temperature plastic tubing, and the ATH10KBL2AT65S is the sealed version of ATH10KBL2AT65. Sealed thermistors can be used in non-corrosive liquid for tem...(more)
