Low Distortion, High Speed Rail-to-Rail Input/Output Amplifier Known Good Die AD8028-KGD-CHIP Many rail-to-rail input amplifiers have an input stage that switches FEATURES from one differential pair to another as the input signal crosses a High speed threshold voltage, which causes distortion. The AD8028-KGD- 190 MHz, 3 dB bandwidth (G = +1) CHIP has a unique feature that allows the user to select the 100 V/s slew rate input crossover threshold voltage through the SELECT pin. Low distortion This feature controls the voltage at which the complementary 120 dBc 1 MHz SFDR transistor input pairs switch. The AD8028-KGD-CHIP also has 80 dBc 5 MHz SFDR intrinsically low crossover distortion. With its wide supply Selectable input crossover threshold voltage range (2.7 V to 12 V) and wide bandwidth (190 MHz), Low noise the AD8028-KGD-CHIP amplifier is designed to work in a 4.3 nV/Hz variety of applications where speed and performance are needed on 1.6 pA/Hz low supply voltages. The AD8028-KGD-CHIP has a disable Low offset voltage: 900 V max mode that is controlled via the SELECT pin. Low power: 6.5 mA/amplifier supply current Disable mode The AD8028-KGD-CHIP is rated to work over the industrial Wide supply range: 2.7 V to 12 V temperature range of 40C to +125C. Known good die (KGD): these die are fully guaranteed to Additional application and technical information can be found data sheet specifications in the AD8028 data sheet. APPLICATIONS Filters ADC drivers Level shifting Buffering Professional video Low voltage instrumentation GENERAL DESCRIPTION 1 The AD8028-KGD-CHIP is a high speed amplifier with rail-to- rail input and output that operates on low supply voltages and is optimized for high performance and wide dynamic signal range. The AD8028-KGD-CHIP has low noise (4.3 nV/Hz, 1.6 pA/Hz) and low distortion (120 dBc at 1 MHz). In applications that use a fraction of or the entire input dynamic range and require low distortion, the AD8028-KGD-CHIP is an ideal choice. 1 Protected by U.S. patent numbers 6,486,737B1 6,518,842B1 Rev.
