Micrel Semiconductor Develops the MIC860 Operational Amplifier
Micrel Semiconductor (San Jose, CA) has developed a 4MHz rail-to-rail operational amplifier that operates from a 2.7V supply while consuming 81uW. The new MIC860 provides a 5MHz gain-bandwidth product while consuming a 30uA supply current. Its packaging is Micrel's Teeny SC70-5.
The MIC860 is unity-gain stable. It is specified at supply voltages of 2.7V and 5V. Input-offset voltage is typically 5mV. Large-signal voltage gain is 91dB, PSRR is 79dB and CMRR is 77dB. The device has a 3V/us slew rate and is suitable for use in portable equipment, cellular phones, PDAs and MP3 players.
"Our previously introduced MIC820 set a new standard for low-power op amps, achieving one-tenth the power consumption of similar-speed devices," said Scott Brown, linear and rf business unit manager. "The new MIC860 consumes similar power to the MIC820 but operates down to lower voltages and has improved PSRR, CMRR and open-loop gain."
The MIC860 is priced at $1.02 in 1,000-piece quantities. Samples are currently available, and production quantities are available in eight weeks ARO.
