Description
The TDC1047 is a 20 Msps (Megasample per second)
full-parallel (flash) analog-to-digital converter, capable of
converting an analog signal with full-power frequency
components up to 7 MHz into 7-bit digital words. Use of
a sample-and-hold circuit is not necessary. All digital inputs
and outputs are TTL compatible.
The TDC1047 consists of 127 clocked latching comparators,
combining logic, and an output buffer register. A single
convert signal controls the conversion operation. The unit
can be connected to give either true or inverted outputs in
binary or offset two’s complement coding.
The TDC1047 is pin and function compatible with the
TDC1027, and offers increased performance with lower
power dissipation.
