• Very low voltage noise 2.8 nV/√Hz @ 1 kHz
• Rail-to-rail output swing
• Low input bias current: 2 nA maximum
• Very low offset voltage: 12 μV typical

• Wide bandwidth: 10 MHz typical
• ±5 V to ±18 V operation

The AD8676 precision operational amplifier offers ultralow offset, drift, and voltage noise combined with very low input bias currents over the full operating temperature range. The AD8676 is a precision, wide bandwidth op amp featuring rail- to-rail output swings and very low noise. Operation is fully specified from ±5 V to ±15 V.

The AD8676 features a rail-to-rail output like that of the OP184, but with wide bandwidth and even lower voltage noise, com-bined with the precision and low power consumption like that of the industry-standard OP07 amplifier. Unlike other low noise, rail-to-rail op amps, the AD8676 has very low input bias current and low input current noise.

With typical offset voltage of only 12 μV, offset drift of 0.2 μV/°C, and noise of only 0.10 μV p-p (0.1 Hz to 10 Hz), the AD8676 is perfectly suited for applications where large error sources cannot be tolerated. Precision instrumentation, PLL and other precision filter circuits, position and pressure sensors, medical instrumentation, and strain gage amplifiers benefit greatly from 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.

The smaller packages and low power consumption afforded by the AD8676 allow maximum channel density or minimum board size for space-critical equipment.

The AD8676 is specified for the extended industrial temperature range (−40°C to +125°C). The AD8676 is available in the 8-lead MSOP, and the popular 8-lead, narrow SOIC; both of which are lead-free packages. MSOP packaged devices are only available in tape and reel format.For the single version of this ultraprecision, rail-to-rail op amp, see the AD8675 data sheet.The AD8675 and AD8676 are members of a growing series of low noise op amps offered by Analog Devices, Inc.

The AD823A is a dual precision, 17 MHz, JFET input op amp manufactured in the extra fast complementary bipolar (XFCB) process. The AD823A can operate from a single supply of 3 V to 36 V or from dual supplies of ±1.5 V to ±18 V. It has true single-supply capability with an input voltage range extending below ground in single-supply mode. Output voltage swing extends to within 20 mV of each rail for IOUT ≤ 100 μA, providing outstanding output dynamic range. It also has a linear output current of 40 mA, 0.5 V from the supply rails.An offset voltage of 700 μV maximum, an offset voltage drift of 1 μV/°C, and typical input bias currents of 0.3 pA provide dc precision with source impedances up to 1 GΩ. The AD823A provides 17 MHz, −3 dB bandwidth, and a 30 V/μs slew rate with a low supply current of only 2.6 mA per amplifier. It also provides low input voltage noise of 14 nV/√Hz and −108 dB SFDR at 20 kHz. The AD823A has low input capacitances (0.6 pF differential and 1.3 pF common mode) and drives more than 500 pF of direct capacitive load as a follower. This lets the amplifier handle a wide range of load conditions.This combination of ac and dc performance, plus the outstanding load drive capability, results in an exceptionally versatile amplifier for applications such as ADC drivers, high speed active filters, and other low voltage, high dynamic range systems.The AD823A is available over the industrial temperature range of −40°C to +85°C and is offered in an 8-lead SOIC package and an 8-lead MSOP package.APPLICATIONS Battery-powered precision instrumentation Photodiode preamps Active filters 12-bit to 16-bit data acquisition systems Medical instrumentation
