LMV712

LMV712 Low Power, Low Noise, High Output, RRIO Dual Operational Amplifier with Independent Shutdown February 2002 LMV712 Low Power, Low Noise, High Output, RRIO Dual Operational Amplifier with Independent Shutdown General Description The LMV712 duals are high performance BiCMOS operational amplifiers intended for applications requiring Rail-to-Rail inputs combined with speed and low noise. They offer a bandwidth of 5MHz and a slew rate of 5V/µs and can handle capacitive loads of up to 200pF without oscillation. The LMV712 offers two independent shutdown pins. This feature allows disabling of each device separately and reduces the supply current to less than 1µA typical. The output voltage rapidly ramps up smoothly with no glitch as the amplifier comes out of the shutdown mode. The LMV712 with the shutdown feature is offered in space saving 10-Bump micro SMD and 10 pin Leadless Leadframe Package (LLP) packages. It is also offered in 10 lead MSOP package. These packages are designed to meet the demands of small size, low power, and low cost required by cellular phones and similar battery operated portable electronics.
