Micrel Semiconductor Inc. (San Jose, CA) announced its new MIC918 and MIC919 op amps that operate at high speeds while consuming low power. Both are voltage-feedback, unity-gain stable devices and are housed in SC70-5 packages.
The op amps achieve a slew-rate of 1.5kV/µs while drawing only 550µA and 360µA, respectively. The MIC918 has a gain-bandwidth product of 51MHz, and the MIC919 has a gain-bandwidth product of 27MHz.
The devices have a 60-degree phase margin at unity gain, which increases with load capacitance. They are specified for supply voltages of ±5V and ±9V. PSRR is 104dB for the MIC918 and 105dB for the MIC919; CMRR is 91dB and 87dB; and AVOL is 93dB and 92dB, respectively.
