Tiny op amps optimised for speedy
slewing
Two high speed op amps from Micrel - MIC918 and MIC919 - achieve a slew-rate of 1500V/us while consuming just 550 and 360uA, respectively.
Two high speed op amps from Micrel - MIC918 and MIC919 - achieve a slew rate of 1500V/us while consuming just 550 and 360uA, respectively Both op amps are voltage-feedback, unity-gain stable devices and are housed in SC70-5 packaging

Micrel has boosted the output capability of the industry's simplest surface-mount DC/DC switching convertor to 2A while retaining the device's original SO-8 packaging.
Dual and triple 135MHz low-power op amps
Consuming just 2.4mA per op amp, the MIC915 dual and MIC916 triple op amps extend Micrel's premier family of high-speed, low-power op amps for power-sensitive high-speed applications.
The MIC918 has a gain-bandwidth product of 51MHz and the MIC919 has a gain-bandwidth product of 27MHz.
As with all other members of Micrel's MIC91x op amp family, they achieve higher speed at lower power than competing devices.
"No other op amps available today are close to achieving this combination of power consumption and speed", said Scott Brown, Linear and RF Business Unit Manager.
"Earlier op amps in this series optimised gain-bandwidth product.
These latest additions are optimised for maximum slew rate.
With the MIC918 and MIC919, we have dramatically increased slew rate while significantly reducing supply current".
Stability - often an issue for high speed op amps - is excellent in all MIC91x parts.
They were designed from the beginning for stable operation and ease of use and are capable of driving loads of any capacitance.
The MIC918 and MIC919 have 60 degrees of phase margin at unity gain, and this actually increases with load capacitance.
The MIC918 and MIC919 are specified for supply voltages of +/-5 and +/-9V.
PSRR is 104dB for the MIC918 and 105dB for the MIC919, and CMRR is 91dB for the MIC918 and 87dB for the MIC919.
AVOL is 93dB for the MIC918 and 92dB for the MIC919.
The MIC918 and MIC919 are provided in SC70-5 packaging and are priced at $1.40 in 1k quantities.
Samples are available immediately, and production quantities are available in 8 weeks.
