The ADA4850-1/ADA4850-21 are low price, high speed, voltage feedbacks rail-to-rail output op amps with ultralow power-down. Despite their low price, the ADA4850-1/ADA4850-2provide excellent overall performance and versaTIlity. The175 MHz, −3 dB bandwidth and 220 V/μs slew rate make theseamplifiers well-suited for many general-purpose, high speedapplicaTIons. 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-supplycapability, allowing input signals to extend 200 mV below thenegaTIve 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 theextended temperature range of −40°C to +125°C.
