SOA Calculator for Temperature Controllers
SOA Calculator for Laser Diode Drivers
|
|
The SOA (Safe Operating Area) curve combines the current, voltage and power limit effects for a
product. The curve illustrates the unsafe operating area where a product can be damaged due to
thermal stress on the output power stage.This tool will allow you to draw the SOA curve for a
Wavelength Electronics product and, optionally, to also draw the load line for your specific
application to easily determine whether your application falls within the safe operating area.

WTC3243 Circuit Design Calculator
|
|
Quickly design the WTC3243 Temperature Controller into your thermoelectric or resistive heater application. The WTC3243 Circuit Design Calculator automatically calculates; TEC (thermoelectric cooler) heat and cool current limits or resistive heater heating current limit, PI loop configuration, and temperature sensor bias and gain resistor values. Easily configure the desired setpoint temperature in degrees Celsius using thermistors (using the Steinhart-Hart equation), Pt RTD, AD590, and LM335 type temperature sensors.

WLD3343 Circuit Design Calculator
|
|
Optimize the WLD3343 Laser Diode Driver for your laser diode application. The WLD3343 Circuit Design Calculator automatically calculates: LD (laser diode) current limit, LD current sense, and PD (photodiode) current sense resistor values. Configure the WLD3343 for any laser diode type and adjust the setpoint operating current in LD forward current in constant current mode or PD current in constant power mode.
