Beschreibung von ADC14155QML-SP
The ADC14155QML-SP is a high-performance CMOS analog-to-digital converter capable of converting analog input signals into 14-bit digital words at rates up to 155 MSPS. This converter uses 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. A unique sample-and-hold stage yields a full-power bandwidth of 1.1 GHz. The ADC14155 operates from dual 3.3-V and 1.8-V power supplies and consumes 967 mW of power at 155 MSPS.
The separate 1.8-V supply for the digital output interface allows lower power operation with reduced noise. A power-down feature reduces the power consumption to 5 mW with the clock input disabled, while still allowing fast wake-up time to full operation. The differential inputs provide a full scale differential input swing equal to 2 times the reference voltage. A stable 1-V internal voltage reference is provided, or the ADC14155 can be operated with an external reference. The Clock mode (differential versus single-ended) and output data format (offset binary versus 2’s complement) are pin-selectable. A duty cycle stabilizer maintains performance over a wide range of clock duty cycles.
The ADC14155QML-SP is available in a 48-lead thermally enhanced multi-layer ceramic quad package and operates over the military temperature range of –55°C to +125°C.
