DESCRIPTION
The TDA8707 is a CMOS triple 6-bit video low-power
analog-to-digital converter (ADC) for RGB signals.
It converts the analog inputs into 6-bit binary coded digital
words at a sampling rate of 35 MHz. All analog signal
inputs are clamped.
Analog-to-digital converter
The TDA8707 implements 3 independent 6-bit
analog-to-digital converters in CMOS process. These
converters use a full-flash approach.
Clamping feature
An internal clamping circuit is provided in each of the
3 analog channels. The analog pins INR, ING and INB are
switched, through series capacitors, to on-chip clamping
levels during an active pulse on the clamp input CLP.
Clamping level in the R, G and B channels is Code 0.
Input buffers
Internal buffers are provided to drive the analog-to-digital
converter inputs. Their ratio can be adjusted externally at
1.5 or 2.0 with select input SLT.
QUICK REFERENCE DATA
Notes
1.
The number of effective bits is measured with a clock frequency of 35 MHz. This value is given for a 4.43 MHz
frequency on the R, G and B channels.
The external resistor (value 15 k
) between V
DDA
and CLREF, fixing internal static currents, influences P
tot
.
