Hi All,
I'll be buying at least 100 LME49860 opamps RSN (real soon new) This gets me into the under $3.00 USD per device range.
The offer is: If you want some of these I will add your request onto my order and charge you actual cost plus shipping and any paypal fees.
I'll be ordering the 8 pin dip package.
The datasheet is at: http://cache.national.com/ds/LM/LME49860.pdf
List price is $5 each and some fool is selling 2 for 12.95 on eBay.
Why use this opamp? Well it does handle 22v rails and has great specs as well as sounding good to many ears. And $3 is not bad!
Here is the National writeup:
The LME49860 is part of the ultra-low distortion, low noise, high slew rate operational amplifier series optimized and fully specified for high performance, high fidelity applications. Combining advanced leading-edge process technology with state-of-the-art circuit design, the LME49860 audio operational amplifiers deliver superior audio signal amplification for outstanding audio performance. The LME49860 combines extremely low voltage noise density (2.7nV/ √^Hz) with vanishingly low THD+N (0.00003%) to easily satisfy the most demanding audio applications. To ensure that the most challenging loads are driven without compromise, the LME49860 has a high slew rate of ±20V/μs and an output current capability of ±26mA. Further, dynamic range is maximized by an output stage that drives 2kΩ loads to within 1V of either power supply voltage and to within 1.4V when driving 600Ω loads.
The LME49860's outstanding CMRR (120dB), PSRR (120dB), and VOS (0.1mV) give the amplifier excellent operational amplifier DC performance.
The LME49860 has a wide supply range of ±2.5V to ±22V. Over this supply range the LME49860 maintains excellent common-mode rejection, power supply rejection, and low input bias current. The LME49860 is unity gain stable. This Audio Operational Amplifier achieves outstanding AC performance while driving complex loads with values as high as 100pF.
