Product Details

The ADA4661-2 is a dual, precision, rail-to-rail input/output amplifier optimized for low power, high bandwidth, and wide operating supply voltage range applications.

The ADA4661-2 performance is guaranteed at 3.0 V, 10 V, and 18 V power supply voltages. It is an excellent selection for applications that use single-ended supplies of 3.3 V, 5 V, 10 V, 12 V and 15 V, and dual supplies of ±2.5 V, ±3.3 V, and ±5 V. It uses the Analog Devices, Inc., patented DigiTrim® trimming technique, which achieves low offset voltage. Additionally, the unique design architecture of the ADA4661-2 allows it to have excellent power supply rejection, common-mode rejection, and offset voltage when operating in the common-mode voltage range of −VSY + 1.5 V to +VSY − 1.5 V.

The ADA4661-2 is specified over the extended industrial temperature range (−40°C to +125°C) and is available in 8-lead MSOP and 8-lead LFCSP (3 mm × 3 mm) packages.

Applications

  • Current shunt monitors
  • Active filters
  • Portable medical equipment
  • Buffer/level shifting
  • High impedance sensor interfaces
  • Battery powered instrumentation

Great OP. I use it as buffer amplifier in our voltage reference standard. The offset voltage drift with temp is about one tenth of our specifications and the supply voltage is sufficiently high to be able to feed at 15 volts, the same as the reference. The low offset current allows us to better filter the reference noise using the technique of bootstrap The small size together with high precision resistors enables us to specify an output voltage of 10 V with 1ppm for °C drift in standard lab envviroment

Being used as a variable gain buffer & level shifter in our prototype application. Measuring less than 100uV total output offset voltage with +/-5V supplies, which is significantly better than two other low cost op-amps tried previously. No problem with output droop close to supply rails. PSRR is also excellent. Overall highly recommended.
