These devices do not require symmetrical supplies; they only require a minimum supply voltage of +4.5V (±2.25V). For VS less than ±3.5V, the common-mode input range does not include midsupply.

OPA140 OPA2140, OPA4140 SBOS498A – JULY 2010 – REVISED AUGUST 2010 www.ti.com BASIC NOISE CALCULATIONS Figure 35 illustrates both noninverting (A) and inverting (B) op amp circuit configurations with gain. In circuit configurations with gain, the feedback network resistors also contribute noise. In general, the current noise of the op amp reacts with the feedback resistors to create additional noise components.

OPA140 OPA2140, OPA4140 www.ti.com SBOS498A – JULY 2010 – REVISED AUGUST 2010 PHASE-REVERSAL PROTECTION The OPA140, OPA2140, and OPA4140 family has internal phase-reversal protection. Many FET- and bipolar-input op amps exhibit a phase reversal when the input is driven beyond its linear common-mode range. This condition is most often encountered in noninverting circuits when the input is driven beyond the specified common-mode voltage range, causing the output to reverse into the opposite rail.

OPA140 OPA2140, OPA4140 www.ti.com SBOS498A – JULY 2010 – REVISED AUGUST 2010 Figure 38 depicts a specific example where the input voltage, VIN, exceeds the positive supply voltage (+VS) by 500mV or more. Much of what happens in the circuit depends on the supply characteristics. If +VS can sink the current, one of the upper input steering diodes conducts and directs current to +VS. Excessively high current levels can flow with increasingly higher VIN.
