Catalyst Semiconductor, Inc. has added a new 32-tap device to its extensive family of over 35 Digitally Programmable Potentiometers (DPP™). The CAT5126 offers one-time wiper programmability via a ...

The CAT5114 digital potentiometer is a pin-for-pin replacement for Intersil’s X9315, but offers the added choice of the very small 2 x 2.5 TDFN package. The CAT5114 is also functionally equivalent to ...

The circuit shown in Figure 1 implements a programmable 0- to 20-mA precision current source. The REF192 low-headroom 2.5-V voltage reference (U1) can source up to 30 mA. An AD5280 digital ...
