GENERAL DESCRIPTION

The AD9246 is available in a 48-lead LFCSP_VQ and is specified

over the industrial temperature range (−40°C to +85°C).

The AD9246 is a monolithic, single 1.8 V supply, 14-bit, 80 MSPS/

105 MSPS/125 MSPS analog-to-digital converter (ADC), featuring

a high performance sample-and-hold amplifier (SHA) and on-chip

voltage reference. The product uses a multistage differential

pipeline architecture with output error correction logic to

provide 14-bit accuracy at 125 MSPS data rates and guarantees

no missing codes over the full operating temperature range.

PRODUCT HIGHLIGHTS

1. The AD9246 operates from a single 1.8 V power supply

and features a separate digital output driver supply to

accommodate 1.8 V to 3.3 V logic families.

The wide bandwidth, truly differential SHA allows 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 AD9246 is suitable for applications in communications,

imaging, and medical ultrasound.

2. The patented SHA input maintains excellent performance

for input frequencies up to 225 MHz.

3. The clock DCS maintains overall ADC performance over a

wide range of clock pulse widths.

4. A standard serial port interface supports various product

features and functions, such as data formatting (offset

binary, twos complement, or Gray coding), enabling the

clock DCS, power-down, and voltage reference mode.

A differential clock input controls all internal conversion cycles.

A duty cycle stabilizer (DCS) compensates for wide variations in

the clock duty cycle while maintaining excellent overall ADC

performance.

5. The AD9246 is pin-compatible with the AD9233, allowing

a simple migration from 12 bits to 14 bits.
