Figure 2. 16-Lead, 3 mm 3 mm LFCSP GENERAL DESCRIPTION The ADA4850-1/ADA4850-2 are low price, high speed, voltage The ADA4850-1/ADA4850-2 are designed to work in the feedbacks rail-to-rail output op amps with ultralow power-down. extended temperature range of 40C to +125C. Despite their low price, the ADA4850-1/ADA4850-2 provide 2 excellent overall performance and versatility. The 175 MHz, 1 3 dB bandwidth and 220 V/s slew rate make these amplifiers well-suited for many general-purpose, high speed applications. 0 The ADA4850-1/ADA4850-2 are designed to operate at supply 1 voltages as low as 2.7 V and up to 6 V at 2.4 mA of supply 2 current per amplifier. In power-down mode, the supply current is less than 150 nA, ideal for battery-powered applications. 3 The ADA4850-1/ADA4850-2 family provides users with a true 4 single-supply capability, allowing input signals to extend G = +1 = 5V V S 200 mV below the negative rail and to within 2.2 V of the 5 R = 1k L V = 0.1V p-p positive rail. The output of the amplifier can swing within OUT 6 80 mV of either supply rail. 1 10 100 1000 FREQUENCY (MHz) With its combination of low price, excellent differential gain Figure 3. Small Signal Frequency Response (0.12%), differential phase (0.09), and 0.1 dB flatness out to 14 MHz, these amplifiers are ideal for video applications. Rev.
