The LTC2238/LTC2237/LTC2236 are 10-bit 65Msps/40Msps/25Msps, low power 3V A/D converters designed for digitizing high frequency, wide dynamic range signals. The LTC2238/LTC2237/LTC2236 are perfect for demanding imaging and communications applications with AC performance that includes 61.8dB SNR and 85dB SFDR for signals at the Nyquist frequency.DC specs include ±0.1LSB INL (typ), ±0.05LSB DNL (typ) and ±0.5LSB INL, ±0.5LSB DNL over temperature. The transition noise is a low 0.07LSBRMS.A single 3V supply allows low power operation. A separate output supply allows the outputs to drive 0.5V to 3.3V logic.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.ApplicationsWireless and Wired Broadband CommunicationImaging SystemsUltrasoundSpectral AnalysisPortable Instrumentation

The LTC2240-12 is a 170Msps, sampling 12-bit A/D converter designed for digitizing high frequency, wide dynamic range signals. The LTC2240-12 is perfect for demanding communications applications with AC performance that includes 65.6dB SNR and 80dB SFDR. Ultralow jitter of 95fsRMSallows IF undersampling with excellent noise performance.DC specs include ±0.6LSB INL (typ), ±0.4LSB DNL (typ) and no missing codes over temperature.The digital outputs can be either differential LVDS, or single-ended CMOS. There are three format options for the CMOS outputs: a single bus running at the full data rate or two demultiplexed buses running at half data rate with either interleaved or simultaneous update. A separate output power supply allows the CMOS output swing to range from 0.5V to 2.625V.The ENC+and ENC–inputs may be driven differentially or single ended with a sine wave, PECL, LVDS, TTL, or CMOS inputs. An optional clock duty cycle stabilizer allows high performance over a wide range of clock duty cycles.BitsLTC2240-1010LTC2240-1212ApplicationsWireless and Wired Broadband CommunicationCable Head-End SystemsPower Amplifier LinearizationCommunications Test Equipment
