Low Distortion, High SpeedRail-to-Rail Input/Output AmplifierKnown Good DieADA4897-2-KGDFEATURESGENERAL DESCRIPTIONHigh speed The ADA4897-2-KGD1 is a high speed amplifier with rail-to- 230 MHz, –3 dB bandwidth (G = +1) rail input and output that operates on low supply voltages and 120 V/µs slew rate is optimized for high performance and a wide dynamic signal Low distortion range. The ADA4897-2-KGD has low noise (1 nV/√Hz, −93 dBc at 1 MHz SFDR 2.8 pA/√Hz) and low distortion (−93 dBc at 1 MHz). In −61 dBc at 5 MHz SFDR applications that use a fraction of or the entire input dynamic Low noise range and require low distortion, the ADA4897-2-KGD is an 1 nV/√Hz voltage noise ideal choice. 2.8 pA/√Hz current noise Many rail-to-rail input amplifiers have an input stage that switches Low offset voltage: 500 µV maximum from one differential pair to another as the input signal crosses a Low power: 3.2 mA/amplifier supply current maximum threshold voltage, which causes distortion. The ADA4897-2-KGD Disable mode has a unique feature that al ows the user to select the input Wide supply range: 3 V to 10 V crossover threshold voltage through the DISABLEx pin. This Known good die (KGD): these die are fully guaranteed todata sheet specifications feature controls the voltage at which the complementary transistor input pairs switch. The ADA4897-2-KGD also has APPLICATIONS intrinsically low crossover distortion. With its wide supply Low noise preamplifiers voltage range (3 V to 10 V) and wide bandwidth (230 MHz), Ultrasound amplifiers the ADA4897-2-KGD amplifier is designed to work in a variety PLL loop filters of applications where speed and performance are needed on low Active filters supply voltages. The ADA4897-2-KGD has a disable mode that ADC drivers is control ed via the DISABLEx pin. Low voltage instrumentation The ADA4897-2-KGD is rated to work over the industrial DAC buffers temperature range of –40°C to +125°C.
