The board size for space-critical equipment. AD8676 is a precision, wide bandwidth op amp featuring rail- The AD8676 is specified for the extended industrial temperature to-rail output swings and very low noise. Operation is fully range (40C to +125C). The AD8676 is available in the 8-lead specified from 5 V to 15 V. MSOP, and the popular 8-lead, narrow SOIC both of which are The AD8676 features a rail-to-rail output like that of the OP184, lead-free packages. MSOP packaged devices are only available in tape and reel format. but with wide bandwidth and even lower voltage noise, com- bined with the precision and low power consumption like that For the single version of this ultraprecision, rail-to-rail op amp, of the industry-standard OP07 amplifier. Unlike other low see the AD8675 data sheet. noise, rail-to-rail op amps, the AD8676 has very low input bias current and low input current noise. The AD8675 and AD8676 are members of a growing series of low noise op amps offered by Analog Devices, Inc. With typical offset voltage of only 12 V, offset drift of 0.2 V/C, and noise of only 0.10 V p-p (0.1 Hz to 10 Hz), the AD8676 is Table 1. Voltage Noise perfectly suited for applications where large error sources Package 0.9 nV 1.1 nV 1.8 nV 2.8 nV 3.8 nV cannot be tolerated. Precision instrumentation, PLL and other Single AD797 AD8597 ADA4004-1 AD8675 AD8671 precision filter circuits, position and pressure sensors, medical Dual AD8599 ADA4004-2 AD8676 AD8672 instrumentation, and strain gage amplifiers benefit greatly from Quad ADA4004-4 AD8674 the very low noise, low input bias current, and wide bandwidth. Many systems can take advantage of the low noise, dc precision, and rail-to-rail output swing provided by the AD8676 to maxi- mize SNR and dynamic range. Rev.
