Overview
The AD871SE/883B is a monolithic 12-bit, 5 MSPS analog-to-digital converter manufactured by Analog Devices Inc. It integrates a high-performance track-and-hold amplifier and voltage reference on-chip. Utilizing a multistage differential pipelined architecture with error correction logic, the device ensures 12-bit accuracy at sampling rates up to 5 MSPS. The component guarantees no missing codes across its full operating temperature range. It features a two's complement binary output and an out-of-range indicator. The part is housed in a 28-lead side brazed ceramic DIP package.
Feature Summary
- Monolithic 12-Bit 5 MSPS A/D Converter
- Low Noise: 0.17 LSB RMS Referred to Input
- No Missing Codes Guaranteed Over Full Temperature Range
- Complete On-Chip Track-and-Hold Amplifier and Voltage Reference
Applications
- High-speed data acquisition systems
- Precision instrumentation requiring low noise performance
- Industrial control applications demanding reliable ADC conversion
Part Context
The AD871SE/883B is a military-grade (883B) variant of the AD871 series. It is pin-compatible with the AD872, allowing for interchangeability in designs where system requirements may change between 5 MSPS and 10 MSPS operation. The 883B suffix indicates compliance with MIL-STD-883 standards for microelectronics.
Replacement Considerations
The AD872 is a confirmed pin-compatible substitute offering 10 MSPS operation. Designers should verify if the higher speed of the AD872 meets power and thermal constraints compared to the AD871.
