This Design Idea mates a precision current source IC with precision difference amp chips to create a programmable current source or sink. The resistor-programmable current source/sink in Figure 1 ...

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 ...

Large analog systems that present many loads to a voltage-reference source can often demand more current than a single reference IC can deliver. However, if the reference IC includes force and sense ...

Designers charged with creating precision analog front ends and signal chains know that the performance of the voltage reference—whether a discrete standalone device or one that’s embedded in a ...

Linear Technology has announced the LT6658, a precision voltage reference that incorporates two high current output buffers. Based on a 2.5V bandgap voltage reference, each output can be separately ...

CMOS current reference circuits play a critical role in modern integrated circuits by providing a stable and reproducible current source that remains unaffected by variations in supply voltage, ...
