Texas Instruments Unveils Three New Chips for AI Data Centers: Nanosecond Telemetry and 800V Power Protection
Texas Instruments launched the ADC34DSO75 and other components to reduce AI data center downtime through nanosecond-scale remote monitoring and integrated high-voltage power management.
Texas Instruments announced three new analog solutions for AI data centers on October 12, 2026, at the Open Compute Project (OCP) Global Summit. These products aim to address challenges such as power instability, inadequate real-time monitoring, and signal degradation that arise as AI workloads increase in volume and complexity.
The flagship product, the ADC34DSO75, is a 3-gigasample-per-second (GSPS) analog-to-digital converter. TI claims it is the industry's highest-performance ADC of its kind, enabling 24/7, low-power, event-based remote monitoring at nanosecond resolution. According to the company, this is thousands of times faster than current solutions, allowing for the real-time detection and capture of transient fault events that cause costly downtime. As the first solution to offer fully remote, event-based telemetry, it eliminates the need for on-site debugging and oscilloscopes, providing hyperscalers with unmatched remote diagnostic capabilities at a fraction of the size and cost of conventional methods.
The LMI800PS is the industry's first 800V isolated hot-swap controller. It replaces a complex discrete solution requiring five integrated circuits with a single high-density package that delivers in-rush current and power path protection. By integrating an isolated bias supply and PMBus telemetry, the controller reduces board area by more than 60% and simplifies high-voltage designs. It meets safety standards with 5kVrms reinforced isolation and more than 8mm creepage, supporting both ±400V and 800V distributions for diverse rack architectures.
The third product, the LMK6B, is a bulk acoustic wave (BAW)-based oscillator that delivers best-in-class jitter performance and power-supply rejection ratio (PSRR). As data center transmission rates approach 3.2Tbps, the margin for timing error shrinks significantly, and even minute jitter can increase bit error rates. The LMK6B achieves 9.6 femtoseconds of jitter at 625MHz, ensuring reliable performance and preserving signal integrity for next-generation AI-driven networking infrastructures.
