LT1993-4 - 900MHz 低失真、低噪声差分放大器/ADC 驱动器(AV = 4V/V)

The LT1993-4 is designed to meet the demanding requirements of communications transceiver applications. It can be used as a differential ADC driver, a general-purpose differential gain block, or in any other application requiring differential drive. The LT1993-4 can be used in data acquisition systems required to function at frequencies down to DC.

The LT1993-4 operates on a 5V supply and consumes 100mA. It comes in a compact 16-lead 3 × 3 QFN package and operates over a -40°C to 85°C temperature range.
