Figure 1.
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.
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.
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.
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.
