ADC10D020

Dual 10-Bit, 20 MSPS, 150 mW A/D Converter

General Description

Features

n Internal sample-and-hold

n Internal reference capability

n Dual gain settings

n Offset correction

The ADC10D020 is a dual low power, high performance

CMOS analog-to-digital converter that digitizes signals to 10

bits resolution at sampling rates up to 30 MSPS while con-

suming a typical 150 mW from a single 3.0V supply. No

missing codes is guaranteed over the full operating tempera-

ture range. The unique two stage architecture achieves 9.5

Effective Bits over the entire Nyquist band at 20 MHz sample

rate. An output formatting choice of straight binary or 2’s

complement coding and a choice of two gain settings eases

the interface to many systems. Also allowing great flexibility

n Conversion Rate

To ease interfacing to most low voltage systems, the digital

output power pins of the ADC10D020 can be tied to a

separate supply voltage of 1.5V to 3.6V, making the outputs

— Fast Recovery Standby Mode

from which recovery is less than 1 ms. Bringing the STBY

(Standby) pin high places the converter into a standby mode

where power consumption is about 27 mW and from which

recovery is 800 ns.

Applications

n Digital Video

n CCD Imaging

The ADC10D020’s speed, resolution and single supply op-

eration makes it well suited for a variety of applications,

including high speed portable applications.

Operating over the industrial (−40˚ ≤ T_A≤ +85˚C) tempera-

ture range, the ADC10D020 is available in a 48-pin TQFP. An

evaluation board is available to ease the design effort.
