You can generate a variable dc reference voltage with a DAC or with a PWM (pulse-width-modulation) signal from your controller (Figure 1). The accuracy of the voltage source that the ...
DPGAs (digitally programmable-gain amplifiers) amplify or attenuate analog signals, which maximizes an ADC’s dynamic range. Most monolithic DPGAs, such as the Linear Technology LTC6910 and the ...
It’s rare in 2023 for an instrument to be entirely analog, instead it’s more normal for a front-end to feed the analog-to-digital converter (ADC) in a microcontroller. Typically the front-end will do ...
