5MHz rail-to-rail op amp consumes 90%
less power
A tiny 5MHz operational amplifier with rail-to-rail output, that consumes one-tenth the power and occupies half the space of competing devices is now available from Micrel Semiconductor.

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.
(Most existing op amps at this speed typically consume 200uA, and many consume even more!) Also, Micrel's Teeny SC70-5 packaging is approximately one-half the size of a SOT23-5 package.
(Most existing devices are still offered only in larger 8-pin packages.) The MIC820 is very easy to use.
It is both unity-gain stable and able to drive capacitive loads.
The device is specified for a supply voltage of 5V.
Input offset voltage is 1mV (typical), large-signal voltage gain is 72dB, power-supply rejection ratio is 70dB and common-mode rejection ratio is 50dB.
"Micrel is once again setting a new standard for lower power consumption for op amps", says Scott Brown, Linear and RF Business Unit Manager.
"Our MIC91x family set a new standard for low power in the 105 to 350MHz range.
The company is now applying this expertise to lower-speed, single-supply devices".
The MIC820 is supplied in SC70-5 packaging and priced at $1.02 in 1k quantities.
