CXA1166K

E90406-ST

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 50

Ω loads

Structure

Bipolar silicon monolithic IC

Applications

• Digital oscilloscopes

• Other apparatus requiring ultrahigh-speed A/D

conversion
