Notes:
1. Absolute maximum ratings are limiting values applied individually while all other parameters are within specified operating conditions. Functional operation under any of these conditions is NOT implied.
2. Applied voltage must be current limited to specified range.
3. Forcing voltage must be limited to specified range.
4. Current is specified as positive when flowing into the device.


Description

The TDC1044A is a 25 Msps (Megasample per second) fullparallel analog-to-digital converter, capable of converting an analog signal with full-power frequency components up to 12.5 MHz into 4-bit digital words. Use of a sample-and-hold circuit is not necessary for operation of the TDC1044A. All digital inputs and outputs are TTL compatible.

The TDC1044A consists of 15 latching comparators, encoding logic, and an output register. A single convert signal controls the conversion operation. Output formats are true/inverted binary or true/inverted offset two's complement codes.
