The ADA4850-1/ADA4850-2YCPZ-R2 are low price, high speed, voltagefeedbacks rail-to-rail output op amps with ultralow power-down.Despite their low price, the ADA4850-1/ADA4850-2YCPZ-R2 provideexcellent overall performance and versatility. The 175 MHz,−3 dB bandwidth and 220 V/μs slew rate make these amplifierswell-suited for many general-purpose, high speed applications.
The ADA4850-1/ADA4850-2YCPZ-R2 are designed to operate at supplyvoltages as low as 2.7 V and up to 6 V at 2.4 mA of supplycurrent per amplifier. In power-down mode, the supply currentis less than 150 nA, ideal for battery-powered applications.
The ADA4850-1/ADA4850-2YCPZ-R2 family provides users with a truesingle-supply capability, allowing input signals to extend200 mV below the negative rail and to within 2.2 V of thepositive rail. The output of the amplifier can swing within80 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 to14 MHz, these amplifiers are ideal for video applications.
The ADA4850-1/ADA4850-2YCPZ-R2 are designed to work in theextended temperature range of −40°C to +125°C.
