LTC2295

The LTC2295 is a 14-bit 10Msps, low power dual 3V A/D converter designed for digitizing high frequency, wide dynamic range signals. The LTC2295 is perfect for demanding imaging and communications applications with AC performance that includes 74.4dB SNR and 90dB SFDR for signals well beyond the Nyquist frequency.DC specs include ±1.2LSB INL (typ), ±0.5LSB DNL (typ) and no missing codes over temperature. The transition noise is a low 1LSBRMS.A single 3V supply allows low power operation. A separate output supply allows the outputs to drive 0.5V to 3.3V 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.

The LTC2295 has some absolute maximum ratings.OVDD=VDD.The supply voltage (VDD) is 4V.The digital output ground voltage (OGND) is -0.3V to 1V.The analog input voltage is 0.3V to (VDD +0.3V).The digital input voltage is 0.3V to (VDD +0.3V).The digital output voltage is 0.3V to (OVDD +0.3V).The power dissipation is 1500mW.The operating temperature range LTC2295C is 0 to 70.The operating temperature range LTC2295l is -40 to 85.The storage temperature range is65 to 125.The lead temperature (soldering,10 sec) is 300.
