Product specification
6-bit high-speed dual Analog-to-Digital
Converter (ADC)
TDA8705
FEATURES
2 times 6-bit resolution
Sampling rate up to 40 MHz
High signal-to-noise ratio over a large analog input
frequency range (5.8 effective bits at 10 MHz full-scale
input at f
clk
= 40 MHz
TTL output
Two separated inputs (AC-coupling)
TTL compatible digital inputs
Low-level AC clock input signal allowed
Internal reference voltage regulator
(external reference regulation possible)
Power dissipation only 250 mW (typical)
Low analog input capacitance, no buffer amplifier
required
No sample-and-hold circuit required.
APPLICATIONS
High-speed analog-to-digital conversion for:
DBS (Digital Broadcast Satellite)
QPSK (Quadrature Phase Shift Keying) demodulation
Video.
GENERAL DESCRIPTION
The TDA8705 is a 6-bit high-speed dual analog-to-digital
converter (ADC) for satellite video and other applications.
It converts the two analog input signals into two 6-bit
binary-coded digital words at a maximum sampling rate of
40 MHz. All digital inputs and outputs are TTL compatible,
although a low-level sine wave clock input signal is
allowed.
