6.1.1 Operating Voltage

OPA137 op amps can be operated on power supplies as low as ±2.25 V. Performance remains excellent with power supplies ranging from ±2.25 V to ±18 V (+4.5 V to +36 V single supply). Most parameters vary only slightly throughout this supply voltage range. Quiescent current and short-circuit current vs supply voltage are shown in Section 5.5.

Operation at very low supply voltage (VS ≤ ±3 V) requires careful attention to ensure that the common-mode voltage remains within the linear range, VCM = (V–)+3 V to (V+). Inputs may need to be biased above ground in accordance with the common-mode voltage range restrictions for linear operation.
