Product Details
The ADA4855-3 (triple) is a single-supply, rail-to-rail output operational amplifier. It provides excellent high speed performance with 410 MHz, −3 dB bandwidth and a slew rate of 870 V/μs. It has a wide input common-mode voltage range that extends from 0.2 V below ground to 1 V below the positive rail.In addition, the output voltage swings within 100 mV of either supply rail, making this rail-to-rail operational amplifier easy to use on single-supply voltages as low as 3.3 V.The ADA4855-3 offers a typical low power of 7.8 mA per amplifier and is capable of delivering up to 57 mA of load current. It also features a power-down function for power sensitive applications that reduces the supply current down to 1 mA.
The ADA4855-3 is available in a 16-lead LFCSP and is designed to work over the extended industrial temperature range of −40°C to +105°C.

Design Tools
Analog Filter Wizard
Use the Analog Filter Wizard to design low-pass, high-pass, or band-pass filters with actual op amps in minutes. As you progress through the design process, you can observe the characteristics of your filter design from ideal specifications to real world circuit behavior. Quickly evaluate the tradeoffs in op amp specifications - including gain-bandwidth, noise, and supply current – to determine the best filter design for your requirements.
Analog Photodiode Wizard
Use Photodiode Wizard to design a transimpedance amplifier circuit to interface with a photodiode. Select a photodiode from the library included in the tool, or enter custom photodiode specifications. Quickly observe tradeoffs between Bandwidth, Peaking (Q), and ENOB/SNR. Modify circuit parameters, and immediately see results in plots for pulse response, frequency response, and noise gain.
VRMS/dBm/dBu/dBV calculators
A utility to convert between standard units of power measurement and signal strength.
Power Dissipation vs Die Temp
This tool estimates die temperature and power dissipation based on the supply voltages, ambient temperature, load characteristics, and package thermal data.
