ADADC80-Z-12

Analog To Digital Converters (ADC) Overview

The ADADC80-Z-12 is a 12-bit successive-approximation analog-to-digital converter (ADC) housed in a 32-lead side-brazed ceramic DIP package. Designed for operation with ±12 V analog supplies and +5 V digital logic, it features a maximum conversion time of 25 μs and a linearity error of ±0.012%. The device integrates an internal clock, comparator, and a precision 6.3 V reference. It supports bipolar input ranges of ±2.5 V, ±5 V, or ±10 V, as well as unipolar ranges of 0 to +5 V or 0 to +10 V. Digital outputs are provided in parallel complementary binary formats.

Analog To Digital Converters (ADC) Feature Summary

• Integrated monolithic 12-bit feedback DAC ensures high reliability and reduced chip count
• Laser-trimmed internal buried Zener reference provides stable 6.3 V output
• Short-cycle capability allows resolution reduction for faster throughput
• Fully DTL and TTL compatible digital inputs and outputs

Analog To Digital Converters (ADC) Applications

• High-throughput data acquisition systems requiring fast conversion rates
• Industrial control applications utilizing ±12 V power supply architectures
• Precision measurement instruments requiring guaranteed monotonicity
• Modular electronic systems demanding industry-standard pin configurations

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix to confirm the ±12 V supply rating, as standard models utilize ±15 V. Confirm RoHS compliance status, as this specific variant is noted as non-compliant. Ensure the procurement source provides the original manufacturer datasheet to validate the hybrid IC construction and pinout compatibility before integration into existing designs.

Analog To Digital Converters (ADC) Selection Notes

Select this component when system architecture requires ±12 V analog supplies rather than the standard ±15 V configuration. Evaluate the need for short-cycle functionality if lower resolution speeds up processing. Consider the external calibration requirements for offset and gain adjustments using potentiometers. Verify that the parallel digital interface matches the host system's data bus width and timing constraints.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADADC80 family of complete 12-bit ADCs manufactured by Analog Devices. It utilizes a hybrid IC design combining MSI digital and linear chips with a monolithic DAC. The 'Z' suffix specifically denotes the version optimized for ±12 V analog supply rails, distinguishing it from the standard ADADC80-12 which operates at ±15 V.

Analog To Digital Converters (ADC) Replacement Considerations

The ADADC80-12 serves as the direct functional equivalent but requires ±15 V supplies instead of ±12 V. Other 12-bit SAR converters may require significant circuit redesign due to differences in pin configuration, reference integration, and digital interface protocols.
