ADC168M102RRHBTSEP

Analog To Digital Converters (ADC) Overview

The ADC168M102RRHBTSEP is a radiation-tolerant, simultaneous sampling SAR ADC manufactured by Texas Instruments. It features eight pseudo-differential or four fully differential input channels, organized into two pairs for concurrent signal acquisition. The device operates at a sampling rate of 1 MSPS with 16-bit resolution. Key electrical specifications include a signal-to-noise ratio (SNR) of 93 dB and a total harmonic distortion (THD) of -98 dB. It supports flexible power supply ranges, includes programmable auto-sequencers, and integrates data storage capabilities for oversampling applications.

Analog To Digital Converters (ADC) Feature Summary

• Radiation tolerance: SEL immune up to LET = 43MeV-cm2/mg at 125°C; TID rated to 30krad (Si).
• Eight pseudo-differential or four fully differential inputs with simultaneous sampling of two channels.
• High AC performance: 93 dB SNR and -98 dB THD.
• Integrated dual-channel programmable and buffered 2.5V reference voltage sources.

Analog To Digital Converters (ADC) Applications

• Defense systems requiring radiation-hardened data conversion.
• Aerospace instrumentation and satellite payloads.
• Harsh environment monitoring where single-event effects are a concern.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADC168M102R family of radiation-tolerant ADCs. The 'SEP' suffix indicates Space Enhanced Plastic packaging, which ensures controlled baseline manufacturing, extended product lifecycle, and traceability suitable for long-term defense and space missions. It utilizes gold wire bonding and NiPdAu lead finishes.

Analog To Digital Converters (ADC) Replacement Considerations

For non-radiation-hardened alternatives, the standard commercial version ADC168M102R may be considered if environmental constraints allow. Verify pin compatibility and software configuration differences when migrating from the SEP variant.
