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.
