PRODUCT DESCRIPTION

The AD9215 is a family of monolithic, single 3 V supply, 10-bit,

65/80/105 MSPS analog-to-digital converters (ADC). This family

features a high performance sample-and-hold amplifier (SHA)

and voltage reference. The AD9215 uses a multistage differential

pipelined architecture with output error correction logic to pro-

vide 10-bit accuracy at 105 MSPS data rates and to guarantee no

missing codes over the full operating temperature range.

Fabricated on an advanced CMOS process, the AD9215 is avail-

able in both a 28-lead surface-mount plastic package and a

32-lead chip scale package and is specified over the industrial

temperature range of −40°C to +85°C.

PRODUCT HIGHLIGHTS

1. The AD9215 operates from a single 3 V power supply and

features a separate digital output driver supply to accom-

modate 2.5 V and 3.3 V logic families.

2. Operating at 105 MSPS, the AD9215 core ADC consumes

a low 120 mW; at 80 MSPS, the power dissipation is 104

mW; and at 65 MSPS, the power dissipation is 96 mW.

3. The patented SHA input maintains excellent performance

for input frequencies up to 200 MHz and can be config-

ured for single-ended or differential operation.

4. The AD9215 is part of several pin compatible 10-, 12-, and

14-bit low power ADCs. This allows a simplified upgrade

from 10 bits to 12 bits for systems up to 80 MSPS.

The wide bandwidth, truly differential sample-and-hold ampli-

fier (SHA) allows for a variety of user-selectable input ranges

and offsets including single-ended applications. It is suitable for

multiplexed systems that switch full-scale voltage levels in

successive channels and for sampling single-channel inputs at

frequencies well beyond the Nyquist rate. Combined with

power and cost savings over previously available ADCs, the

AD9215 is suitable for applications in communications, imag-

ing, and medical ultrasound.

A single-ended clock input is used to control all internal conversion

cycles. A duty cycle stabilizer compensates for wide variations in the

clock duty cycle while maintaining excellent performance. The digital

output data is presented in straight binary or twos complement for-

mats. An out-of-range signal indicates an overflow condition, which

can be used with the MSB to determine low or high overflow.

5. The clock duty cycle stabilizer maintains converter per-

formance over a wide range of clock pulse widths.

6. The out of range (OR) output bit indicates when the signal

is beyond the selected input range.
