AD8676BRMZ Description

Over the entire operating temperature range, the AD8676BRMZ precision operational amplifier provides ultralow offset, drift, and voltage noise, as well as very low input bias currents. The AD8676BRMZ is a high-precision, wide-bandwidth op-amp with low noise and rail-to-rail output swings. From 5 V to 15 V, the operation is thoroughly explained. The AD8676BRMZ has a rail-to-rail output similar to the OP184, but with a wider bandwidth and reduced voltage noise, as well as the precision and low power consumption of the industry-standard OP07. The AD8676BRMZ features a very low input bias current and low input current noise, compared to comparable low noise, rail-to-rail op-amps. The AD8676BRMZ is well suited for applications where substantial error sources cannot be tolerated, with a typical offset voltage of only 12V, offset drift of 0.2V/°C, and noise of only 0.10V p-p (0.1 Hz to 10 Hz). The very low noise, low input bias current, and wide bandwidth benefit precision instruments, PLL and other precision filter circuits, position and pressure sensors, medical instrumentation, and strain gage amplifiers.
