ADA4895-2ARMZ-R7

ADA4895-2 is a dual channel, high speed voltage feedback amplifier. It is an ideal solution in a variety of applications, including ultrasound, low noise preamplifiers, and drivers of high performance ADCs. The Analog Devices, Inc., proprietary next generation SiGe bipolar process and innovative architecture enables the high performance of these amplifiers. The wide supply voltage range of 3V to 10V make this amplifier ideal candidates for systems that require large dynamic range, high gain, precision, and high speed. It is used in applications such as low noise preamplifier, ultrasound amplifiers, PLL loop filters, high performance analogue-to-digital converter (ADC) drivers, digital-to-analogue converter (DAC) buffers.
