Fast-slewing op amps keep the power low
Micrel Semiconductor reckons its two latest high-speed op amps provide an order of magnitude improvement in the ratio of slew rate to power consumption when compared with competing devices.

World's simplest buck regulator boosted to 2A
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 devices combine high slew rates of 3000 and 3200V/us with low power consumption of 550 and 360uA, respectively.
Decompensation enables the MIC920 and MIC921 to achieve an even higher slew rate and gain-bandwidth product for the same power consumption while still maintaining unity-gain stability.
The MIC920 has a gain-bandwidth product of 80MHz and the MIC921 has a gain-bandwidth product of 45MHz.
Both are capable of driving unlimited capacitance and are housed in SC70-5 packaging.
"The MIC918 and MIC919 set a new standard for the ratio of power consumption to slew rate", said Scott Brown, Linear and RF Business Unit Manager.
"The MIC920 and MIC921 put Micrel a full order of magnitude ahead of all comparable devices".
Stability, which is often an issue for high speed op amps, is excellent in all MIC91x op amps as they have been designed for stable operation and ease of use and are capable of driving loads of any capacitance.
The MIC920 and MIC921 are both specified for supply voltages of +/-2.5 and +/-9V.
PSRR is 104dB for the MIC920 and 105dB for the MIC921, and CMRR is 91dB for the MIC920 and 87dB for the MIC921.
AVOL is 93dB for the MIC920 and 92dB for the MIC921.
The MIC920 and MIC921 in SC70-5 packaging are priced at $1.25 in 1000 piece quantities.
Samples are available immediately, and production quantities are available in 8 weeks ARO.
