9.1.2 Achieving an Output Level of Zero Volts

Certain single-supply applications require the op‑amp output to swing from 0 V to a positive full-scale voltage and have high accuracy. An example is an op amp employed to drive a single-supply ADC having an input range from 0 V to 3.3 V. Rail-to-rail output amplifiers with very light output loading can achieve an output level within few millivolts of 0 V (or V+ at the high end), but not true 0 V. Furthermore, the deviation from 0 V only becomes greater as the required load current increases. This increased deviation is a result of limitations of the CMOS output stage.

When a pulldown resistor is connected from the amplifier output to a negative voltage source, the TLVx365 can achieve an output level of 0 V, and even a few millivolts below 0 V. Figure 9-3 shows a circuit using this technique.

GUID-20230613-SS0I-BVLK-WFFR-53X2WQDFNT2G-low.gif Figure 9-3 Swing-to-Ground

A pulldown current of approximately 500 μA is required when TLVx365 is connected as a unity-gain buffer. Pulldown resistor RL is calculated from RL = [(VO − VNEG) / (500 μA)].

Figure 9-33 shows the offset voltage vs output swing.
