CXA1166K
8-bit 250 MSPS Flash A/D Converter
Description
The CXA1166K is an 8-bit ultrahigh-speed flash
A/D converter IC capable of digitizing analog signals
at a maximum rate of 250 MSPS. The digital I/O
level of this A/D converter is compatible with the
ECL 100K/10KH/10K.
This IC is pin-compatible with the conventional
CXA1076AK/CXA1176K/CXA1176AK, and can
replace the conventional models easily. Compared
with the conventional models, the CXA1166K has a
greatly improved performance because of the new
circuit design and carefully considered layout.
Features
Differential linearity error: ±0.5 LSB or less
Integral linearity error: ±0.5 LSB or less
Built-in integral linearity compensation circuit
Ultrahigh-speed operation with maximum conver-
sion rate of 250 MSPS
Low input capacitance: 18pF
Wide analog input bandwidth: 250MHz (full-scale
input, standard)
Single power supply: –5.2V
Low power consumption: 1.4W (Typ.)
Low error rate
Good temperature characteristics
Capable of driving 50loads
68 pin LCC (Ceramic)
Structure
Bipolar silicon monolithic IC
Applications
Digital oscilloscopes
Other apparatus requiring ultrahigh-speed A/D
conversion
