ADC12L063

12-Bit, 62 MSPS, 354 mW A/D Converter with Internal

Sample-and-Hold

General Description

The ADC12L063 is a monolithic CMOS analog-to-digital con-

verter capable of converting analog input signals into 12-bit

digital words at 62 Megasamples per second (MSPS), mini-

mum. This converter uses a differential, pipelined architec-

ture with digital error correction and an on-chip sample-and-

hold circuit to minimize die size and power consumption

while providing excellent dynamic performance. Operating

on a single 3.3V power supply, this device consumes just

354 mW at 62 MSPS, including the reference current. The

Power Down feature reduces power consumption to just 50

mW.

The differential inputs provide a full scale input swing equal

to ±V

REF with the possibility of a single-ended input. Full use

of the differential input is recommended for optimum perfor-

mance. For ease of use, the buffered, high impedance,

single-ended reference input is converted on-chip to a differ-

ential reference for use by the processing circuitry. Output

data format is 12-bit offset binary.

This device is available in the 32-lead LQFP package and

will operate over the industrial temperature range of −40˚C to

+85˚C.
