PRODUCT DESCRIPTION
The AD9260 is a 16-bit, high-speed oversampled analog-to-
digital converter (ADC) that offers exceptional dynamic range
over a wide bandwidth. The AD9260 is manufactured on an
advanced CMOS process. High dynamic range is achieved with
an oversampling ratio of 8
×
through the use of a proprietary
technique that combines the advantages of sigma-delta and
pipeline converter technologies.
The AD9260 is a switched-capacitor ADC with a nominal full-
scale input range of 4 V. It offers a differential input with 60 dB
of common-mode rejection of common-mode signals. The sig-
nal range of each differential input is
±
1 V centered on a 2.0 V
common-mode level.
The on-chip decimation filter is configured for maximum per-
formance and flexibility. A series of three half-band FIR filter
stages provide 8
×
decimation filtering with 85 dB of stopband
attenuation and 0.004 dB of passband ripple. An onboard digi-
tal multiplexer allows the user to access data from the various
stages of the decimation filter.
The on-chip programmable reference and reference buffer am-
plifier are configured for maximum accuracy and flexibility. An
external reference can also be chosen to suit the user’s specific
dc accuracy and drift requirements.
The AD9260 operates on a single +5 V supply, typically con-
suming 585 mW of power. A power scaling circuit is provided
allowing the AD9260 to operate at power consumption levels as
low as 150 mW at reduced clock and data rates. The AD9260 is
available in a 44-lead MQFP package and is specified to operate
over the industrial temperature range.
PRODUCT HIGHLIGHTS
The AD9260 is fabricated on a very cost effective CMOS
process. High-speed, precision mixed-signal analog circuits are
combined with high-density digital filter circuits.
The AD9260 offers a complete single-chip 16-bit sampling
ADC with a 2.5 MHz output data rate in a 44-lead MQFP.
Selectable Internal Decimation Filtering
—The AD9260
provides a high-performance decimation filter with 0.004 dB
passband ripple and 85 dB of stopband attenuation. The filter
is configurable with options for 1
×
, 2
×
, 4
×
, and 8
×
decimation.
Power Scaling
—The AD9260 consumes a low 585 mW of power
at 16-bit resolution and 2.5 MHz output data rate. Its power
can be scaled down to as low as 150 mW at reduced clock rates.
Single Supply
— Both of the analog and digital portions of the
AD9260 can operate off of a single +5 V supply simplifying
system power supply design. The digital logic will also accom-
modate a single +3 V supply for reduced power.
