LTC2225CUH#PBF

LTC2225 is a 12bit, 10Msps low power 3V ADC. It designed for digitizing high frequency, wide dynamic range signals. It is perfect for demanding imaging and communications applications with AC performance that includes 71.3dB SNR and 90dB SFDR for signals well beyond the Nyquist frequency. DC specs include ±0.3LSB INL (typ), ±0.15LSB DNL (typ) and no missing codes over temperature. The transition noise is a low 0.25LSBRMS. A single 3V supply allows low power operation. A separate output supply allows the outputs to drive 0.5V to 3.6V logic. A single-ended CLK input controls converter operation. Application includes wireless and wired broadband communication, imaging systems, spectral analysis, portable instrumentation.
