GENERAL DESCRIPTION
The AD9248 is a dual, 3 V, 14-bit, 20 MSPS/40 MSPS/65 MSPS
analog-to-digital converter (ADC). It features dual high
performance sample-and hold amplifiers (SHAs) and an
integrated voltage reference. The AD9248 uses a multistage
differential pipelined architecture with output error correction
logic to provide 14-bit accuracy and to guarantee no missing
codes over the full operating temperature range at up to
65 MSPS data rates. The wide bandwidth, differential SHA
allows for a variety of user-selectable input ranges and offsets,
including single-ended applications. It is suitable for various
applications, including multiplexed systems that switch full-
scale voltage levels in successive channels and for sampling
inputs at frequencies well beyond the Nyquist rate.
Dual single-ended clock inputs are used to control all internal
conversion cycles. A duty cycle stabilizer is available and can
compensate for wide variations in the clock duty cycle, allowing
the converter to maintain excellent performance. The digital
output data is presented in either straight binary or twos
complement format. Out-of-range signals indicate an overflow
condition, which can be used with the most significant bit to
determine low or high overflow.

Fabricated on an advanced CMOS process, the AD9248 is
available in a Pb-free, space saving, 64-lead LQFP or LFCSP and
is specified over the industrial temperature range (−40°C to
+85°C).
PRODUCT HIGHLIGHTS
1. Pin-compatible with the AD9238, 12-bit 20 MSPS/
40 MSPS/65 MSPS ADC.
2. Speed grade options of 20 MSPS, 40 MSPS, and 65 MSPS
allow flexibility between power, cost, and performance to suit
an application.
3. Low power consumption: AD9248-65: 65 MSPS = 600 mW,
AD9248-40: 40 MSPS = 330 mW, and AD9248-20: 20 MSPS =
180 mW.
4. Typical channel isolation of 85 dB @ fIN = 10 MHz.
5. The clock duty cycle stabilizer (AD9248-20/AD9248-40/
AD9248-65) maintains performance over a wide range of
clock duty cycles.
6. Multiplexed data output option enables single-port operation
from either Data Port A or Data Port B.
