description/ordering information (continued)

The LMV981 and LMV982 devices offer shutdown capability for additional power savings. Pulling the SHDN

pin low puts the amplifiers in shutdown, where only 0.156

mA typically is consumed from a 1.8-V supply. In

normal operation with the same 1.8-V supply, 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 LMV981 and LMV982 devices are offered in the latest packaging technology to meet the most demanding

space-constraint applications. The LMV981 is offered in standard SOT-23 and SC-70 packages. The LMV982

is available in the 10-pin MSOP package.

The LMV98x devices are characterized for operation from −40

°C to 125°C, making them universally suited for

commercial, industrial, and automotive applications.
