数据手册.pdf模数转换器 - ADC LTC2299 - Dual 14-Bit, 80Msps Low Power 3V ADC
DESCRIPTION
The LTC®2299 is a 14-bit 80Msps, low power dual 3V A/D converter designed for digitizing high frequency, wide dynamic range signals. The LTC2299 is perfect for demanding imaging and communications applications with AC performance that includes 73dB SNR and 90dB SFDR for signals well beyond the Nyquist frequency. DC specs include ±1.2LSB INL typ, ±0.5LSB DNL typ
and ±5LSB INL, ±1LSB DNL over temperature. The transition noise is a low 1.2LSBRMS.
