Overview
ADC11DS105 Dual 11-Bit, 105 MSPS A/D Converter with Serial LVDS Outputs November 4, 2009 ADC11DS105 Dual 11-Bit, 105 MSPS A/D Converter with Serial LVDS Outputs General Description The ADC11DS105is a high-performance CMOS analog-todigital converters capable of converting two analog input signals into 11-bit digital words at rates up to 105 Mega Samples Per Second (MSPS).
The digital outputs are serialized and provided on differential LVDS signal pairs.
These converters use a differential, pipelined architecture with digital error correction and an on-chip sample-and-hold circuit to minimize power consumption and the external component count, while providing excellent dynamic performance.
The ADC11DS105 may be operated from a single +3.
0 or +3.
3V power supply.
A power-down feature reduces the power consumption to very low levels while still allowing fast wake-up time to full operation.
The differential inputs accept a 2V full scale differential input swing.
A stable 1.
2V internal voltage reference is provided, or the ADC11DS105 can be operated with an external 1.
2V reference.
The selectable duty cycle stabilizer maintains performance over a wide range of clock duty cycles.
A serial interface allows access to the internal registers for full control of the ADC11DS105's functionality.
The ADC11DS105 is available in a 60-lead LLP package and operates over the industrial temperature range of −40°C to +85°C.
