LMV710/LMV711/LMV715 Low Power, RRIO Operational Amplifiers with High Output Current
Drive and Shutdown Option
General Description
The LMV710/LMV711/LMV715 are BiCMOS operational amplifiers with a CMOS input stage. These devices have greater
than RR input common mode voltage range, rail-to-rail output
and high output current drive. They offer a bandwidth of 5 MHz
and a slew rate of 5 V/µs.
On the LMV711/LMV715, a separate shutdown pin can be
used to disable the device and reduces the supply current to
0.2 µA (typical). They also feature a turn on time of less than
10 µs. It is an ideal solution for power sensitive applications,
such as cellular phone, pager, palm computer, etc. In addition, once the LMV715 is in shutdown the output will be “Tristated”.
The LMV710 is offered in the space saving 5-Pin SOT23 Tiny
package. The LMV711/LMV715 are offered in the space saving 6-Pin SOT23 Tiny package.
The LMV710/LMV711/LMV715 are designed to meet the demands of low power, low cost, and small size required by
cellular phones and similar battery powered portable electronics.
