ADA4807-2ARMZ

运算放大器 - 运放 Ultra Low Power 120 MHz High Spd R/R AMP - 运放 Ultra Low Power 120 MHz High Spd R/R AMP

GENERAL DESCRIPTION ADA4807-2ARMZ

The ADA4807-1 (single), ADA4807-2 (dual), and ADA4807-4 (quad) are low noise, rail-to-rail input and output, voltage feedback amplifiers. These amplifiers combine low power, low noise, high speed, and dc precision to provide an attractive solution for a wide range of applications from high resolution data acquisition instrumentation to high performance batterypowered and high component density systems where power consumption is of key importance.
