ADC11C170
11-Bit, 170 MSPS, 1.1 GHz Bandwidth A/D Converter with
CMOS outputs
General Description
The ADC11C170 is a high-performance CMOS analog-to-
digital converter capable of converting analog input signals
into 11-Bit digital words at rates up to 170 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 ADC11C170 operates from
dual +3.3V and +1.8V power supplies and consumes 747 mW
of power at 170 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 while
still allowing fast wake-up time to full operation. In addition
there is a sleep feature which consumes 50 mW of power and
has a faster wake-up time.
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 ADC11C170 can
be operated with an external reference.
Clock mode (differential versus single-ended) and output data
format (offset binary versus 2's complement) are pin-se-
lectable. A duty cycle stabilizer maintains performance over
a wide range of input clock duty cycles.
The ADC11C170 is pin compatible with the ADC11C125, AD-
C12C170, and ADC14155.
It is available in a 48-lead LLP package and operates over the
industrial temperature range of −40°C to +85°C.
