PRODUCT DESCRIPTION
The AD871 is a monolithic 12-bit, 5 MSPS analog-to-digital
converter with an on-chip, high performance track-and-hold
amplifier and voltage reference. The AD871 uses a multistage
differential pipelined architecture with error correction logic to
provide 12-bit accuracy at 5 MSPS data rates and guarantees no
missing codes over the full operating temperature range. The
AD871 is a redesigned variation of the AD872 12-bit, 10 MSPS
ADC, optimized for lower noise in applications requiring sam-
pling rates of 5 MSPS or less. The AD871 is pin compatible
with the AD872, allowing the parts to be used interchangeably
as system requirements change.
The low-noise input track-and-hold (T/H) of the AD871 is ide-
ally suited for high-end imaging applications. In addition, the
T/H’s high input impedance and fast settling characteristics
allow the AD871 to easily interface with multiplexed systems
that switch multiple signals through a single A/D converter. The
dynamic performance of the input T/H also renders the AD871
suitable for sampling single channel inputs at frequencies up to
and beyond the Nyquist rate. The AD871 provides both refer-
ence output and reference input pins, allowing the onboard ref-
erence to serve as a system reference. An external reference can
also be chosen to suit the dc accuracy and temperature drift
requirements of the application. A single clock input is used to
control all internal conversion cycles. The digital output data is
presented 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 AD871 is fabricated on Analog Devices’ ABCMOS-1 pro-
cess, which uses high speed bipolar and CMOS transistors on a
single chip. High speed, precision analog circuits are now com-
bined with high density logic circuits.
The AD871 is packaged in a 28-lead ceramic DIP and a
44-terminal leadless ceramic surface mount package and is
specified for operation from 0

PRODUCT HIGHLIGHTS
The AD871 offers a complete single-chip sampling 12-bit,
5 MSPS analog-to-digital conversion function in a 28-lead DIP
or 44-terminal leadless ceramic surface mount package (LCC).
Low Noise—
The AD871 features 0.17 LSB referred-to-input
noise, producing essentially a “1 code wide” histogram for a
code-centered dc input.
Low Power—
The AD871 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 AD871 is complete with T/H and voltage ref-
erence and is pin-compatible with the AD872 (12-bit, 10 MSPS
monolithic ADC).
Out of Range (OTR)—
The OTR output bit indicates when the
input signal is beyond the AD871’s input range.
