GENERAL DESCRIPTION
The AD9262 is a dual channel, 16-bit analog-to-digital conver-
ter (ADC) based on a continuous time (CT) sigma-delta (Σ-Δ)
architecture that achieves 87 dBc of dynamic range over a
10 MHz input bandwidth. The integrated features and characteris-
tics unique to the continuous time Σ-Δ architecture significantly
simplify its use and minimize the need for external components.
The AD9262 has a resistive input impedance that relaxes the
requirements of the driver amplifier. In addition, a 32× oversam-
pled fifth-order continuous time loop filter significantly attenuates
out-of-band signals and aliases, reducing the need for external
filters at the input.
An external clock input or the integrated integer-N PLL provides
the 640 MHz internal clock needed for the oversampled conti-
nuous time Σ-Δ modulator. On-chip decimation filters and sample
rate converters reduce the modulator data rate from 640 MSPS to a
user-defined output data rate between 30 MSPS and 160 MSPS,
enabling a more efficient and direct interface.

The AD9262 incorporates an integrated dc correction and
quadrature estimation block that corrects for gain and phase
mismatch between the two channels. This functional block
proves invaluable in complex signal processing applications
such as direct conversion receivers.
The digital output data is presented in offset binary, Gray code,
or twos complement format. A data clock output (DCO) is
provided to ensure proper timing with the receiving logic. The
AD9262 has the added feature of interleaving Channel A and
Channel B data onto one 16-bit bus, simplifying on-board routing.
The ADC is available in three different bandwidth options of
2.5 MHz, 5 MHz, and 10 MHz, and operates on a 1.8 V analog
supply and a 1.8 V to 3.3 V digital supply, consuming 600 mW.
The AD9262 is available in a 64-lead LFCSP and is specified
over the industrial temperature range (40°C to +85°C).
PRODUCT HIGHLIGHTS
1.
Continuous time Σ-Δ architecture efficiently achieves high
dynamic range and wide bandwidth.
2.
Passive input structure reduces or eliminates the require-
ments for a driver amplifier.
3.
An oversampling ratio of 32× and high order loop filter
provide excellent alias rejection reducing or eliminating the
need for antialiasing filters.
4.
An integrated decimation filter, sample rate converter, PLL
clock multiplier, and voltage reference provide ease of use.
5.
Integrated dc correction and quadrature error correction.
6.
Operates from a single 1.8 V analog power supply and
1.8 V to 3.3 V output supply.
