The SM73302 is an 88 MHz, precision, low noise, 1.8V CMOS input, decompensated operational amplifier
The SM73302 low noise, CMOS input op amp provides a low input voltage noise density of 5.8 nV/√Hz while consuming only 1.15 mA of quiescent current. The gain of the SM73302 is stabilized at a factor of 10, and the gain-bandwidth (GBW) product is 88 MHz. The SM73302 has a supply voltage range of 1.8V to 5.5V and can operate from a single supply. Featuring a rail-to-rail output stage, the SM73302 is part of a family of precision amplifiers ideal for a variety of instrumentation applications.
The SM73302 provides optimum performance in low voltage and low noise systems. A CMOS input stage, typical input bias currents in the range of a few femtoamps, and input common-mode voltage range (including ground) make the SM73302 ideal for AN5276 low-power sensor applications that require high speed.
The SM73302 is manufactured using an advanced VIP50 process. The SM73302 is available in a 5-pin SOT-23 package.
