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 generalpurpose, high speed applications. 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 l...
