Before working as an applications engineer, I worked as an IC test development engineer here at TI. One of my projects was to characterize an I2C temperature sensor. After writing some software, I threw together a hand-wired prototype board. I was in…

Power supply rejection ratio (PSRR) describes how well an operational amplifier (op amp) rejects variations in power supply voltage. PSRR is defined as the shift in offset per volt of shift in power…
