The input common-mode voltage range of the TLV900x-Q1 family extends 100mV beyond the supply rails for the full supply voltage range of 1.8V to 5.5V. This performance is achieved with a complementary input stage: an N-channel input differential pair in parallel with a P-channel differential pair, as shown in the Functional Block Diagram section. The N-channel pair is active for input voltages close to the positive rail, typically (V+) – 1.4V to 100mV above the positive supply, whereas the P-channel pair is active for inputs from 100mV below the negative supply to approximately (V+) – 1.4V. There is a small transition region, typically (V+) – 1.2V to (V+) – 1V, in which both pairs are on. This 100mV transition region can vary up to 100mV with process variation. Thus, the transition region (with both stages on) can range from (V+) – 1.4V to (V+) – 1.2V on the low end, and up to (V+) – 1V to (V+) – 0.8V on the high end. Within this transition region, PSRR, CMRR, offset voltage, offset drift, and THD can degrade compared to device operation outside this region.
