description/ordering information (continued)

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

mA 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 MSOP and SOIC packages. The LMV934 is available in the traditional SOIC and

TSSOP packages.

The LMV93x devices are characterized for operation from −40

°C to 125°C, making the part universally suited

for commercial, industrial, and automotive applications.
