GENERAL DESCRIPTION

The AD8428 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.
