SOIC-8 (R-8) and MSOP-8 (RM-8) 190 MHz (G = −10)Low power34 mW or 6.7 mA typical for 5 V supply The AD8021 allows the user to choose the gain bandwidth Output disable feature, 1.3 mA product that best suits the application. With a single capacitor, Low distortion the user can compensate the AD8021 for the desired gain with −93 dBc second harmonic, fC = 1 MHz little trade-off in bandwidth. The AD8021 is a well-behaved −108 dBc third harmonic, fC = 1 MHz amplifier that settles to 0.01% in 23 ns for a 1 V step. It has a fast DC precision overload recovery of 50 ns. 1 mV maximum input offset voltage 0.5 μV/°C input offset voltage drift The AD8021 is stable over temperature with low input offset Wide supply range, 5 V to 24 V voltage drift and input bias current drift, 0.5 μV/°C and 10 nA/°C, Low price respectively. The AD8021 is also capable of driving a 75 Ω line Small packaging with ±3 V video signals. Available in SOIC-8 and MSOP-8 The AD8021 is both technically superior and priced considerably
