Product Details
The ADA4853-1/ADA4853-2/ADA4853-3 are low power, low cost, high speed, rail-to-rail output op amps with ultralow power disables that are ideal for portable consumer electronics. Despite their low price, the ADA4853-1/ADA4853-2/ADA4853-3 provide excellent overall performance and versatility. The 100 MHz, −3 dB bandwidth, and 120 V/μs slew rate make these amplifiers well-suited for many general-purpose, high speed applications.
The ADA4853-1/ADA4853-2/ADA4853-3 voltage feedback op amps are designed to operate at supply voltages as low as 2.65 V and up to 5 V using only 1.4 mA of supply current per amplifier. To further reduce power consumption, the amplifiers are equipped with a power-down mode that lowers the supply current to less than 1.5 μA maximum, making them ideal in battery-powered applications.
The ADA4853-1/ADA4853-2/ADA4853-3 provide users with a true single-supply capability, allowing input signals to extend 200 mV below the negative rail and to within 1.2 V of the positive rail. On the output, the amplifiers can swing within 200 mV of either supply rail.
With their combination of low price, excellent differential gain (0.2%), differential phase (0.10°), and 0.5 dB flatness out to 22 MHz, these amplifiers are ideal for video applications.
The ADA4853-1 is available in a 6-lead SC70, the ADA4853-2 is available in a 16-lead LFCSP_WQ, and the ADA4853-3 is available in both a 16-lead LFCSP_WQ and a 14-lead TSSOP. The ADA4853-1 temperature range is −40°C to +85°C while the ADA4853-2/ADA4853-3 temperature range is −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.
