The ADA4853-1/ADA4853-2/ADA4853-3 are low power, low cost, The ADA4853-1 is available in a 6-lead SC70, the ADA4853-2 is high speed, rail-to-rail output op amps with ultralow power disables available in a 16-lead LFCSP_WQ, and the ADA4853-3 is available in that are ideal for portable consumer electronics. Despite their low both a 16-lead LFCSP_WQ and a 14-lead TSSOP. The ADA4853-1 price, the ADA4853-1/ADA4853-2/ADA4853-3 provide excellent temperature range is −40°C to +85°C while the ADA4853-2/ overall performance and versatility. The 100 MHz, −3 dB ADA4853-3 temperature range is −40°C to +105°C. bandwidth, and 120 V/μs slew rate make these amplifiers well-
