GENERAL DESCRIPTION  
The ADA4850-1, ADA4850-21 are low price, high speed,  
voltage feedback 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/µs  
slew rate make these amplifiers well-suited for many general-  
purpose, high speed applications.  
The ADA4850-1/ADA4850-2 are designed to work in the  
extended temperature range of −40°C to +125°C.

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.

G = +1  
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.

FREQUENCY (MHz)  
With its combination of low price, excellent differential gain  
(0.12%), differential phase (0.09º), and 0.1 dB flatness out to  
14 MHz, these amplifiers are ideal for video applications.
