GENERAL DESCRIPTION
The AD9236 is a monolithic, single 3 V supply, 12-bit, 80 MSPS
analog-to-digital converter featuring a high performance sample-
and-hold amplifier (SHA) and voltage reference. The AD9236
uses a multistage differential pipelined architecture with output
error correction logic to provide 12-bit accuracy at 80 MSPS
and guarantee no missing codes over the full operating
temperature range.
The wide bandwidth, truly differential SHA allows a variety of
user-selectable input ranges and common modes, 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 analog-to-digital converters, the AD9236 is
suitable for applications in communications, imaging, and
medical ultrasound.
A single-ended clock input is used to control all internal
conversion cycles. A duty cycle stabilizer (DCS) compensates
for wide variations in the clock duty cycle while maintaining
excellent overall ADC performance. The digital output data is

presented in straight binary or twos complement formats. An
out-of-range (OTR) signal indicates an overflow condition that
can be used with the most significant bit to determine low or
high overflow. Fabricated on an advanced CMOS process, the
AD9236 is available in a 28-lead TSSOP and a 32-lead LFCSP
and is specified over the industrial temperature range
(40°C to +85°C).
PRODUCT HIGHLIGHTS
1. The AD9236 operates from a single 3 V power supply and
features a separate digital output driver supply to
accommodate 2.5 V and 3.3 V logic families.
2. Operating at 80 MSPS, the AD9236 consumes a low 366 mW.
3. The patented SHA input maintains excellent performance for
input frequencies up to 100 MHz, and can be configured for
single-ended or differential operation.
4. The AD9236 is pin compatible with the AD9215, AD9235,
and AD9245. This allows a simplified migration from 10 bits
to 14 bits and 20 MSPS to 80 MSPS.
5. The DCS maintains overall ADC performance over a wide
range of clock pulse widths.
6. The OTR output bit indicates when the signal is beyond the
selected input range.
