PRODUCT DESCRIPTION
The AD872A is a monolithic 12-bit, 10 MSPS analog-to-digital
converter with an on-chip, high performance track-and-hold
amplifier and voltage reference. The AD872A uses a multistage
differential pipelined architecture with error correction logic to
provide 12-bit accuracy at 10 MSPS data rates and guarantees
no missing codes over the full operating temperature range. The
AD872A is a redesigned version of the AD872 which has been
optimized for lower noise. The AD872A is pin compatible with
the AD872, allowing the parts to be used interchangeably as sys-
tem requirements change.
The low noise input track-and-hold (T/H) of the AD872A is
ideally suited for high-end imaging applications. In addition, the
T/H’s high input impedance and fast settling characteristics al-
low the AD872A to easily interface with multiplexed systems
that switch multiple signals through a single A/D converter. The
dynamic performance of the T/H also renders the AD872A suit-
able for sampling single channel inputs at frequencies up to and
beyond the Nyquist rate. The AD872A provides both reference
output and reference input pins, allowing the onboard reference
to serve as a system reference. An external reference can also be
chosen to suit the dc accuracy and temperature drift require-
ments of the application. A single clock input is used to control
all internal conversion cycles. The digital output data is pre-
sented in twos complement binary output format. An out-of-
range signal indicates an overflow condition, and can be used
with the most significant bit to determine low or high overflow.
The AD872A is fabricated on Analog Devices’ ABCMOS-l
process that utilizes high speed bipolar and CMOS transistors
on a single chip.
The AD872A is packaged in a 28-lead ceramic DIP and a 44-
terminal leadless ceramic surface mount package (LCC). Opera-
tion is specified from 0
°C to +70°C and –55°C to +125°C.
PRODUCT HIGHLIGHTS
The AD872A offers a complete single-chip sampling, 12-bit
10 MSPS analog-to-digital conversion function in a 28-lead DIP
or 44-terminal LCC.
Low Noise—The AD872A features 0.26 LSB rms referred to-
input noise.
Low Power—The AD872A at 1.03 W consumes a fraction of the
power of presently available hybrids.
On-Chip Track-and-Hold (T/H)—The low noise, high imped-
ance T/H input eliminates the need for external buffers and can
be configured for single-ended or differential inputs.
Ease of Use—The AD872A is complete with T/H and voltage
reference and is pin-compatible with the AD872.
Out of Range (OTR)—The OTR output bit indicates when the
input signal is beyond the AD872A’s input range.
