LTC2284IUP#PBF

LTC®2284 is a 14bit 105Msps, low power dual 3V A/D converter designed for digitizing high frequency, wide dynamic range signals. It is perfect for demanding imaging and communications applications with AC performance that includes 72.4dB SNR and 85dB SFDR for signals at the Nyquist frequency. Typical DC specs include ±1.5LSB INL, ±0.6LSB DNL. The transition noise is a low 1.3LSBRMS. 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.

• Integral linearity error is ±1.5LSB (differential analogue input, TA = 25°C)
• Offset error range from -12 to 12mV (TA = 25°C)
• Gain error range from -2.5 to 2.5%FS (external reference, TA = 25°C)
• Typical offset drift is ±10µV/°C (TA = 25°C)
• Analog input range from ±0.5V to ±1V (2.85V <lt/> VDD <lt/> 3.4V, TA = 25°C)
• Typical full power bandwidth is 575MHz (TA = 25°C)
• Typical signal-to-noise ratio is 72.4dB (TA = 25°C, AIN = -1dBFS)
• Typical signal-to-noise plus distortion ratio is 72.2dB (5MHz input, TA = 25°C, AIN = -1dBFS)
• Analog supply voltage range from 2.85 to 3.4V (TA = 25°C)
• 64 lead plastic QFN package, operating temperature range from -40°C to 85°C
