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/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.

The ADA4850-1/ADA4850-2 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 (0.09°), and 0.1 dB flatness out to  
14 MHz, these amplifiers are ideal for video applications.
