The dual comes in an 8-pins SC70 package? I'd never heard of that package ...

Sunnyvale, Calif.— Maxim Integrated Products has introduced the MAX9613/MAX9615, low-power, precision operational amplifiers with rail-to-rail I/O.
The MAX9613/MAX9615 op amps have a unique self-calibration feature that allows offset correction or nulling at any time or temperature. Each time the system is powered up, self-calibration is activated, thereby minimizing system drift errors induced by temperature gradients. This capability saves designers the time and labor normally associated with manual system calibration, while ensuring that the system functions as specified. The MAX9613/MAX9615 are well suited for sensor interfaces in portable industrial and medical applications.
Key highlights:
- VCC = 1.7V to 5.5V (0°C to +70°C)
- VCC = 1.8V to 5.5V (-40°C to +125°C)
- Low 100µV (max) VOS
- Rail-to-Rail Inputs and Outputs
- Low 210µA Supply Current, 1µA in Shutdown
- Autotrim Offset Calibration
- 2.8MHz Bandwidth
- -40ºC to +125ºC automotive temperature range
Pricing: Starts at $0.65 (1000-up, FOB USA).
Availability: The MAX9613/MAX9615 are available in an ultra-small (2mm x 2.2mm), lead-free, 6-/8-pin SC70 package, respectively. Maxim also offers pin-compatible versions (MAX9614/MAX9616) without self-calibration.

Frankly I don't see how exciting this product is. 100uV offset is not very low while the drift after calibration is still 7uV/C max. which I believe can't be regarded as a very nice part. Even if we don't compare to chopper amplifier with way much lower offset and drift, some CMOS op-amp from other vendors can achieve similar or even better performance without any special start-up calibration kind of funny term. I personally like the LTC6081 which has very low offset, drift and noise.

The dual comes in an 8-pins SC70 package? I'd never heard of that package before. It's awfully small though!
