RRIO Op Amp
National Semiconductor Corporation introduces a high-bandwidth, 1V, rail-to-rail input and output (RRIO) CMOS operational amplifier. The LMV951’s combination of bandwidth and low power make it suited for cell phones, handheld devices, portable medical equipment and low-power instrumentation. The LMV951 is believed to be the only a 1 V operational amplifier capable of delivering 2.7 MHz unity-gain bandwidth and maintaining its stability when driving a 500 pF capacitive load. It features low voltage noise of 25 nV/EHz across a temperature range from -40°C to 125°C. These features, coupled with a common-mode rejection ratio (CMRR) of 80 dB and a power supply rejection ratio (PSRR) of 80 dB, make the op amp suitable for applications requiring higher gain and performance.
