ADC12D040

Dual 12-Bit, 40 MSPS, 600 mW A/D Converter with

Internal/External Reference and Sample-and-Hold

General Description

The ADC12D040 is a dual, low power monolithic CMOS

analog-to-digital converter capable of converting analog in-

put signals into 12-bit digital words at 40 Megasamples per

second (MSPS), minimum. This converter uses a differential,

pipelined architecture with digital error correction and an

on-chip sample-and-hold circuit to minimize die size and

power consumption while providing excellent dynamic per-

formance. Operating on a single 5V power supply, the

ADC12D040 achieves 10.9 effective bits at 10 MHz input

and consumes just 600 mW at 40 MSPS, including the

reference current. The Power Down feature reduces power

consumption to 75 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. The

digital outputs for the two ADCs are available on separate

12-bit buses with an output data format choice of offset

binary or 2’s complement.

For ease of interface, the digital output driver power pins of

the ADC12D040 can be connected to a separate supply

voltage in the range of 2.5V to the digital supply voltage,

making the outputs compatible with low voltage systems.

When not converting, power consumption can be reduced by

pulling the PD pin high, placing the converter into the power-

down state where it typically consumes just 75 mW. The

ADC12D040’s speed, resolution and single supply operation

make it well suited for a variety of applications.

This device is available in the 64-lead TQFP package and

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

+85˚C.
