AD8428BRZ Datasheet PDF - ADI

●The AD8428BRZ is an ultralow noise Instrumentation Amplifier designed to accurately measure tiny, high speed signals. It delivers industry-leading gain accuracy, noise and bandwidth. All gain setting resistors for the AD8428 are internal to the part and are precisely matched. Care is taken in both the chip pinout and layout. This results in excellent gain drift and quick settling to the final gain value after the part is powered on. The high CMRR of the AD8428 prevents unwanted signals from corrupting the signal of interest. The pinout of the AD8428 is designed to avoid parasitic capacitance mismatches that can degrade CMRR at high frequencies. The AD8428 is one of the fastest instrumentation amplifiers available. The circuit architecture is designed for high bandwidth at high gain. The AD8428 uses a current feedback topology for the initial preamplifier gain stage of 200, followed by a difference amplifier stage of 10.
