6.3 Feature Description

TL331x family consists of a PNP Darlington pair input, allowing the device to operate with very high gain and fast response with minimal input bias current. The input Darlington pair creates a limit on the input common mode voltage capability, allowing TL331x to accurately function from ground to VCC – 1.5V differential input. In later revisions, a clamp was added around Q3 to mimic the outside-of-input voltage range behavior of the original classic silicon.

The output consists of an open collector NPN (pull-down or low side) transistor. The output NPN will sink current when the negative input voltage is higher than the positive input voltage and the offset voltage. The VOL is resistive and will scale with the output current. Please see the "Output Low Voltage vs. Output Sinking Current" graphs in Typical Characteristics for VOL values with respect to the output current.
