LTC6912CGN-1#PBF

LINEAR TECHNOLOGY  LTC6912CGN-1#PBF  可编程/可变增益放大器, 1 放大器, 2个放大器, 50 MHz, -40 °C, 85 °C, 2.7V 至 10.5V

The is a dual-channel low noise Programmable Gain Amplifier PGA with serial digital interface. It is easy to use and occupy very little PC board space. The gains for both channels are independently programmable using a 3-wire SPI interface to select voltage gains of 0, 1, 2, 5, 10, 20, 50 and 100V/V. All gains are inverting. The LTC6912 family consists of 2 matched amplifiers with rail-to-rail outputs. When operated with unity gain, it will also process rail-to-rail input signals. A half-supply reference generated internally at the AGND pin supports single power supply applications.
