DESCRIPTION

The LMV93x devices are low-voltage low-power operational amplifiers that are well suited for today's low-voltage

and/or portable applications. Specified for operation of 1.8 V to 5 V, they can be used in portable applications

that are powered from a single-cell Li-ion or two-cell batteries. They have rail-to-rail input and output capability for

maximum signal swings in low-voltage applications. The LMV93x input common-mode voltage extends 200 mV

beyond the rails for increased flexibility. The output can swing rail-to-rail unloaded and typically can reach 80 mV

from the rails, while driving a 600-

Ω load (at 1.8-V operation).

During 1.8-V operation, the devices typically consume a quiescent current of 103 µA per channel, and yet they

are able to achieve excellent electrical specifications, such as 101-dB open-loop DC gain and 1.4-MHz gain

bandwidth. Furthermore, the amplifiers offer good output drive characteristics, with the ability to drive a 600-

Ω

load and 1000-pF capacitance with minimal ringing.

The LMV93x devices are offered in the latest packaging technology to meet the most demanding

space-constraint applications. The LMV931 is offered in standard SOT-23 and SC-70 packages. The LMV932 is

available in the traditional SOIC package. The LMV934 is available in the traditional SOIC package and the

TSSOP package.

The LMV93x devices are characterized for operation from –40°C to 125°C, making the part universally suited for

commercial, industrial, and automotive applications.
