AD588TQ/883 Visão geral
A voltage reference is a precision electronic circuit that produces a constant output voltage regardless of load, temperature, or supply variations. It is a fundamental building block in analog and mixed-signal systems, serving as a stable reference for analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and comparators. Voltage references are categorized into series and shunt types; the AD588 is a series reference, which offers lower power consumption and better accuracy than shunt references.
Key features of the AD588TQ/883 include 12-bit absolute accuracy, low temperature coefficient of 3 ppm/°C, and optional fine-trim connections for higher precision. The device operates over a wide supply range and provides both 5V and 10V outputs, which can be programmed via pin strapping. The military-grade temperature range ensures reliable operation in harsh environments.
The AD588 uses a buried Zener diode reference and precision thin-film resistors to achieve its high accuracy. The architecture provides excellent long-term stability and low noise, making it ideal for precision instrumentation and data acquisition systems. The fine-trim capability allows users to adjust the output voltage to meet specific accuracy requirements.
Typical applications include precision data acquisition systems, calibration equipment, and aerospace instrumentation. The AD588TQ/883 is also used in military and aerospace systems where high reliability and accuracy are critical. Its 16-lead CERDIP package provides hermetic sealing, protecting the die from moisture and contaminants.
When designing with the AD588TQ/883, ensure proper decoupling on the input supply and output to maintain stability. The fine-trim pins can be used to adjust output voltage, but care must be taken to avoid introducing noise. The device is available in tube packaging, and pricing is available from authorized distributors.

Notas de projeto
The AD588TQ/883 requires a supply voltage between 10.8V and 36V. For 10V output, ensure the input is at least 10.8V plus dropout. Use a low-noise supply and bypass with 0.1uF and 10uF capacitors close to the V+ and V- pins to maintain stability and reduce noise.
For optimal performance, place the AD588TQ/883 on a dedicated ground plane and keep the output trace short and shielded. Use Kelvin connections for the output sense if high accuracy is required. Avoid routing high-frequency signals near the reference to prevent noise coupling.
Do not exceed the maximum output current of 10 mA. The fine-trim pins should be used with precision resistors to avoid introducing errors. Ensure the CERDIP package is handled properly to avoid thermal stress, and verify the pinout against the datasheet before PCB layout.
