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 °C to +70°C and –55°C to +125 °C. 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. One Technology Way, P.O. Box 9106, Norwood, MA 02062-9106, U.S.A.
