CMC7106Y

CALIFORNIA MICRO DEVICES CMC7106 CMC7106 Low Power Operational Amplifier, RRIO, with Shutdown, SOT23-6 Features • Tiny SOT23-6 package • Guaranteed specs at 2.7V, 3V, and 5V • Low supply current 0.3µA typ. operating. Less than 1µA idle. • Rail-to-Rail Input and Output (RRIO) • Simple shutdown mode (with logic level control) for power savings • 1MHz gain-bandwidth • Input common mode range includes V- and V+ Applications • Test and Measurement Equipment • Cellular Phones • Portable Equipment • Notebooks and PDAs • Electronic Toys Product Description The California Micro Devices CMC7106 is a high performance CMOS operational amplifier in a 6-pin SOT23-6 package. Operating with low supply current, it is ideal for battery operated applications where power, space, and weight are critical considerations. Performance is similar to CAMD’s CMC7101AY SOT Amp, with the addition of a shutdown pin to greatly reduce supply current when idle. The shutdown mode is controlled by an extra pin, and is compatible with most logic family signal levels. Ideal for use in test and measurement equipment and personal electronics such as cellular handsets, pagers, cordless telephones, and other products with limited space and battery power.

The CMC7106 has the additional benefit of reducing power consumption to almost nothing ( Vin - (V+ 0.3 V) ———————————— 5 mA (1) Figure 1. High Side Current Sense Low Current 3.3V Regulator with Disable Over the past few years, power supply voltages in systems, particularly in PC’s, have migrated from 5 volts to 3.3 volts while at the same time, saving power – particularly in portable systems has become a major issue. On the other hand, there are “legacy” devices which still mandate the use of a 5 volt Vcc. Frequently in systems, a finite amount of current is needed for the 3.3 volt IC’s. The circuit shown below provides a stable 3.3 voltage supply derived from the 5 volts at currents up to 100 For V+ (or V-) equal to 2.7 volts and Vin equal to 10 volts, Rs should be chosen for a value of 1.5 KΩ or greater. Shut-down Pin Current Limiting Considerations The Shut-down pin also provides ESD clamp diodes that will be damaged if the signal exceeds the rail by 0.3 volt either from a logic gate or other signal source. If possible, the current should be limited to less than ± 5 mA by inserting a resistor between the gate or source and the Shut-down Pin whose value is determined by Equation (1) above. ©1999 California Micro Devices Corp.
