Frequently Asked Questions
What is the common-mode rejection ratio specification of the TS1872AIYDT and why does it matter for sensor applications?
The TS1872AIYDT specifies a minimum CMRR of 60 dB and a typical CMRR of 80 dB, which is critical for rejecting noise on sensor signal lines in industrial and medical applications. High CMRR ensures that common-mode interference from power supply noise or electromagnetic coupling does not corrupt the differential signal from a 1.8 V rail-powered transducer.
How does the TS1872AIYDT's 0.15 µA bias current benefit high-impedance sensor signal chains?
With a maximum input bias current of 0.15 µA, the TS1872AIYDT introduces minimal loading on high-impedance sources such as pH electrodes, photodiodes, and piezoelectric sensors. This low bias current translates to reduced offset voltage error when the source impedance is in the megohm range, preserving measurement accuracy across the full 1.8 V rail-to-rail output swing.
Which low-voltage portable designs benefit from the TS1872AIYDT's rail-to-rail output on a 1.8 V supply?
Wearable heart rate monitors, portable glucose meters, and IoT environmental sensors powered by 1.8 V LDO rails benefit from the TS1872AIYDT's rail-to-rail output swing. Operating to within millivolts of both supply rails maximizes the usable dynamic range, enabling 12-bit or 16-bit ADC interfaces to sample the full signal amplitude without headroom loss in space-constrained battery-powered designs.
