AD8676BRZ Description

Over the entire operating temperature range, the AD8676BRZ precision operational amplifier provides ultralow offset, drift, and voltage noise, as well as very low input bias currents. The AD8676BRZ is a high-precision, wide-bandwidth op amp with low noise and rail-to-rail output swings. From 5 V to 15 V, operation is thoroughly explained.
The AD8676BRZ datasheet claims that it 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 amplifier. The AD8676BRZ features a very low input bias current and low input current noise, compared to comparable low noise, rail-to-rail op amps.
The AD8676 is ideal 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.
To enhance SNR and dynamic range, many systems can benefit from the AD8676BRZ's low noise, dc accuracy, and rail-to-rail output swing.
The AD8676BRZ's smaller packaging and low power consumption enable maximum channel density or a tiny board size for space-critical devices.
The AD8676BRZ is designed to work in a wide range of temperatures (40°C to +125°C). The AD8676BRZ is offered in two lead-free packages: the 8-lead MSOP and the popular 8-lead narrow SOIC. Only tape and reel format MSOP packed devices are available.
