Features

Description

• 4-bit resolution

• 1/4 LSB non-linearity

• Sample-and-hold circuit not required

• 25 Msps conversion rate

• Selectable output format

The TDC1044A is a 25 Msps (Megasample per second) full-

parallel 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.

• 16-lead DIP and 20-lead PLCC packages

The TDC1044A consists of 15 latching comparators, encod-

ing 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.

Applications

• Digital communications

• Video special effects

• Radar data conversion

• Medical imaging
