AD8675ARZ Description
Over the entire operating temperature range, the AD8675ARZ precision operational amplifier exhibits ultralow offset, drift, and voltage noise, as well as very low input bias currents. The AD8675ARZ 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 AD8675ARZ has a rail-to-rail output similar to the OP184, but with broader bandwidth and reduced voltage noise, as well as the precision and low power consumption of the industry-standard OP07. The AD8675 features a shallow input bias current and low input current noise, compared to comparable low noise rail-to-rail op-amps.
The AD8675ARZ is ideal for applications where substantial error sources cannot be tolerated, with a typical offset voltage of only 10 V, offset drift of 0.2 V/°C, and noise of only 0.10 V p-p (0.1 Hz to 10 Hz). The patented nulling functionality allows a combination of both device and system offset faults up to 3.5 mV (relative to the input) to be adjusted externally for applications with even lower offset tolerances. Unlike prior circuits, the AD8675ARZ allows for this change without altering the amplifier's offset drift, CMRR, or PSRR.
The very low noise, low input bias current, and wide bandwidth serve precision instruments, PLL, and other precision filter circuits, position and pressure sensors, medical instrumentation, and strain gage amplifiers tremendously. To enhance SNR and dynamic range, many systems can benefit from the AD8675ARZ's low noise, dc accuracy, and rail-to-rail output swing. The AD8675ARZ's smaller packaging and low power consumption enable maximum channel density or a tiny board size for space-critical devices. The AD8675ARZ is designed for use in a wide range of industrial temperatures (40°C to +125°C). It's available in the compact 8-lead MSOP and the popular 8-lead, narrow SOIC, RoHS compatible packaging, according to the AD8675ARZ datasheet. Only tape and reel format MSOP-packed devices are available.
