GENERAL DESCRIPTION
The ADA4850-1/ADA4850-2 are low price, high speed, voltage
feedbacks rail-to-rail output op amps with ultralow power-
down. Despite their low price, the ADA4850-1/ADA4850-2
provide excellent overall performance and versatility. The
175 MHz, 3 dB bandwidth and 220 V/s slew rate make these
amplifiers well-suited for many general-purpose, high speed
applications.
The ADA4850-1/ADA4850-2 are designed to operate at supply
voltages as low as 2.7 V and up to 6 V at 2.4 mA of supply
current per amplifier. In power-down mode, the supply current
is less than 150 nA, ideal for battery-powered applications.
The ADA4850 family provides users with a true single-supply
capability, allowing input signals to extend 200 mV below the
negative rail and to within 2.2 V of the positive rail. The output
of the amplifier can swing within 80 mV of either supply rail.
With its combination of low price, excellent differential gain
(0.12%), differential phase (0.09°), and 0.1 dB flatness out to
14 MHz, these amplifiers are ideal for video applications.
The ADA4850-1/ADA4850-2 are designed to work in the
extended temperature range of 40°C to +125°C.
