LTC2291CUP#PBF

LTC2291 is a 12bit low power dual channel A/D converter designed for digitizing high frequency, wide dynamic range signals. A single 3V supply allows low power operation. A separate output supply allows the outputs to drive 0.5V to 3.6V logic. An optional multiplexer allows both channels to share a digital output bus. A single-ended CLK input controls converter operation. An optional clock duty cycle stabilizer allows high performance at full speed for a wide range of clock duty cycles. It is widely used in application such as wireless and wired broadband communication, imaging systems, spectral analysis, portable instrumentation etc.
