Single-Component Thermometers

The DMS-20 and DMS-30 Series of 3½ digit voltmeters are ideal for constructing very accurate digital thermometers with only a single external component —the LM34 or LM35 solid-state, temperature-transducer IC’s. The LM34 and LM35, both available from National Semiconductor, are rugged three-terminal devices designed to make temperature measurements in degrees Fahrenheit or Celsius, respectively. Introduction … Read more

Half-Digits, Resolution, and Digital Panel Meter Display FAQ’s

Some of the more frequently asked (FAQ) display-related questions we receive from first-time users of digital panel meters go something like: “exactly what is a half-digit, anyway?” or, “what’s the resolution of a 3½ digit panel meter?” These questions are one of the motivating reasons for this application note. The “FAQ” style used below will … Read more

Digital PID Compensation

In the last installment, we were halfway through the compensator design for a buck converter. As a quick recap, when designing digital compensators, the true system gain is different from the derived transfer function. In the case of our buck converter, we have to take into consideration the voltage sense resistive divider drop, the ADC … Read more
