ADS1282HKV/EM

Overview

The ADS1282HKV/EM is a radiation-hardness assured, high-resolution delta-sigma analog-to-digital converter (ADC) from the ADS1282-SP series. It features a 4th-order modulator and flexible digital filter supporting data rates from 250 SPS to 4 kSPS. The device includes a low-noise programmable gain amplifier (PGA) with gains of 1 to 64 and a two-channel input multiplexer. It operates on an analog supply of unipolar 5 V or bipolar ±2.5 V, and a digital supply of 1.75 V to 3.6 V. The component achieves 124 dB SNR at 1000 SPS and provides 31-bit resolution without missing codes. It is housed in a 28-pin Ceramic Flat Pack (CFP) package.

Feature Summary

• Radiation hardness assurance up to 50 kRAD (Si) total ionizing dose with single-event latchup immunity.
• Integrated low-noise PGA and two-channel MUX for direct sensor interfacing.
• Flexible digital filter architecture including Sinc, FIR, and IIR options with selectable phase responses.
• On-chip calibration engine for offset and gain scaling.

Applications

• Space satellite temperature and position sensing
• Space satellite precision and scientific applications
• High-accuracy instrumentation

Procurement Notes

Verify that the specific ordering suffix corresponds to the required temperature range and qualification level. The /EM suffix indicates engineering evaluation samples processed to a non-compliant flow without burn-in. These units are tested only to 25°C and are not suitable for flight use, production, or full MIL specified temperature range qualification.

Selection Notes

Select the appropriate variant based on the required operating temperature range. The 5962L1423101VXC variant supports –55°C to 125°C, while the 5962L1423102VXC supports –55°C to 115°C for improved dynamic performance. Ensure the power supply configuration matches the analog voltage requirements of the application.

Part Context

This component belongs to the ADS1282-SP family, which is specifically designed for harsh environment applications requiring radiation tolerance. It shares the core ADC architecture with commercial variants but undergoes specialized processing to meet MIL-PRF-38535 Class V standards.

Replacement Considerations

Direct replacements include other ADS1282-SP variants such as ADS1282IPW or ADS1282IPWR for non-radiation-hardened applications. For space-grade needs, verify compatibility with 5962L1423101VXC or 5962L1423102VXC specifications.
