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).

GENERAL DESCRIPTION

The AD9236 is a monolithic, single 3 V supply, 12-bit, 80 MSPS

analog-to-digital converter featuring a high performance sam-

ple-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 operat-

ing temperature range.

PRODUCT HIGHLIGHTS

1. The AD9236 operates from a single 3 V power supply and

features a separate digital output driver supply to accommo-

date 2.5 V and 3.3 V logic families.

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.

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 pulsewidths.

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

version cycles. A duty cycle stabilizer (DCS) compensates for

wide variations in the clock duty cycle while maintaining excel-

lent overall ADC performance. The digital output data is

6. The OTR output bit indicates when the signal is beyond the

selected input range.
