14-Bit, 155 MSPS, 1.1 GHz Bandwidth A/D Converter
General Description
The ADC14155 is a high-performance CMOS analog-to-dig-
ital converter capable of converting analog input signals into
14-bit digital words at rates up to 155 Mega Samples Per
Second (MSPS). This converter uses a differential, pipelined
architecture with digital error correction and an on-chip sam-
ple-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 +3.3V and +1.8V power supplies and consumes 967 mW
of power at 155 MSPS.
The separate +1.8V supply for the digital output interface al-
lows 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 1.0V
internal voltage reference is provided, or the ADC14155 can
be operated with an external reference.
The ADC14155 can be configured for either single-ended or
differential operation. Clock mode (differential versus single-
ended) and output data format (offset binary versus 2's com-
plement) are pin-selectable. A duty cycle stabilizer maintains
performance over a wide range of clock duty cycles.
The ADC14155 is available in a 48-lead LLP package and
operates over the industrial temperature range of −40°C to
+85°C.
