Thermocouple-to-DMM interface

Thermocouples are economical and rugged devices for temperature measurements. Because of their small size, they respond quickly and are good choices where fast response to temperature changes is important. Type K thermocouples have a wide temperature range. “and are used from cryogenics to jet engine exhaust analysis. The present circuit converts thermocouple outputs into a direct[…]

REF200 from Burr-Brown

Burr-Brown’s REF200 provides in independent 8-pin DIL package two independent current sources, either of which can supply 100 NA and a 1:1 current. mirror. The pinout of the device is shown in Fig. 1. Note that there are no pins for connecting a supply voltage. The correct operation of the current. sources are, however, guaranteed[…]

Simple LDR circuit for automatic light system

  This circuit describes the principle of light dependent resistor (LDR) operation. LDR is actually a device whose sensitivity is based on the intensity of light that is falling on it. The LDR’s resistance decreases whenever intensity of light falling on it increases & vice versa (resistance increases when intensity of falling light decreases). In absence[…]
