ADA4853-3:  Low Power, Rail-to-Rail Output, Video Op Amp with Ultralow Power

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_VQ, and the ADA4853-3 is available in both a 16-lead LFCSP_VQ 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.
