Single-Supply, High Speed, Triple Op Amp with Charge Pump
This triple operational amplifier is designed to operate on supply voltages of 3.3 V to 5 V, using only 42 mA of total quiescent current, including the charge pump. To further reduce the power consumption, it is equipped with a power-down feature that lowers the total supply current to as low as 2.5 mA when the amplifier is not being used. Even in power-down mode, the charge pump can be used to power external components. The maximum output current for external use is 50 mA at −3 V. The amplifier also has a wide input common-mode voltage range that extends from 1.8 V below ground to 1.2 V below the positive rail at a 5 V supply.
The ADA4858-3 is available in a 16-lead LFCSP, and it is designed to work over the extended industrial temperature range of −40°C to +105°C.
Data Sheet, Rev. A, 05/09
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
These evaluation boards are designed to help users evaluate the ADA4853-3. The evaluation board is a BARE BOARD. There are no components or amplifiers soldered to the board. These parts must be obtained separately from the table below or on the product page. Free samples may also be requested. The unpopulated board enables users to quickly customize and prototype a variety of op amp circuits, which minimizes risk and reduces time to market.
The User Guide contains all the required documentation to build the board, including schematics, assembly drawing, and Bill of Materials
