MAX4223MAX4228 19-1230 Rev 2a 6/97 1GHz, Low-Power, SOT23, Current-Feedback Amplifiers with Shutdown General Description Features The MAX4223MAX4228 current-feedback amplifiers Ultra-High Speed and Fast Settling Time: combine ultra-high-speed performance, low distortion, 1GHz -3dB Bandwidth (MAX4223, Gain = +1) and excellent video specifications with low-power oper- 600MHz -3dB Bandwidth (MAX4224, Gain = +2) ation. The MAX4223/MAX4224/MAX4226/MAX4228 1700V/s Slew Rate (MAX4224) have a shutdown feature that reduces power-supply 5ns Settling Time to 0.1% (MAX4224) current to 350A and places the outputs into a high- impedance state. These devices operate with dual sup- Excellent Video Specifications (MAX4223): plies ranging from 2.85V to 5.5V and provide a Gain Flatness of 0.1dB to 300MHz typical output drive current of 80mA. The MAX4223/ 0.01%/0.02 DG/DP Errors MAX4225/MAX4226 are optimized for a closed-loop Low Distortion: gain of +1 (0dB) or more and have a -3dB bandwidth of -60dBc THD (f = 10MHz) c 1GHz, while the MAX4224/MAX4227/MAX4228 are compensated for a closed-loop gain of +2 (6dB) or 42dBm Third-Order Intercept (f = 30MHz) more, and have a -3dB bandwidth of 600MHz (1.2GHz 6.0mA Quiescent Supply Current (per amplifier) gain-bandwidth product). Shutdown Mode: The MAX4223MAX4228 are ideal for professional video 350A Supply Current (per amplifier) applications, with differential gain and phase errors of 100k Output Impedance 0.01% and 0.02, 0.1dB gain flatness of 300MHz, and a 1100V/s slew rate. Total harmonic distortion (THD) of High Output Drive Capability: -60dBc (10MHz) and an 8ns settling time to 0.1% suit 80mA Output Current these devices for driving high-speed analog-to-digital Drives up to 4 Back-Terminated 75 Loads to inputs or for data-communications applications. The low- 2.5V while Maintaining Excellent Differential power shutdown mode on the MAX4223/MAX4224/ Gain/Phase Characteristics MAX4226/MAX4228 makes them suitable for portable and battery-powered applications. Their high output Available in Tiny 6-Pin SOT23 and 10-Pin MAX impedance in shutdown mode is excellent for multiplex- Packages ing applications. The single MAX4223/MAX4224 are available in space- Ordering Information saving 6-pin SOT23 packages. All devices are available in the extended -40C to +85C temperature range. PIN- SOT PART TEMP.
