Texas Instruments (TI) has unveiled the ADC34DSO75, an analog-to-digital converter capable of continuously and remotely monitoring server power lines at nanosecond resolution, to catch the micro-outages that cause downtime in AI data centers. The company announced it on October 12, 2026, at the OCP Global Summit in San Jose, California, alongside an isolated hot-swap controller for 800V power distribution and a low-jitter oscillator for high-speed networks.
TI’s new chips for AI data centers in 20 seconds
- The ADC34DSO75 samples at 3 gigasamples per second to catch nanosecond-level electrical faults.
- The LMI800PS replaces five chips in 800V racks.
- The LMK6B oscillator claims 9.6 femtoseconds of jitter.
- TI hasn’t given pricing, and the ADC is still in preproduction.
The announcement addresses a mostly invisible problem in AI infrastructure. Accelerators draw heavy current at very low voltage with abrupt load swings, which can generate very brief disturbances on power lines. According to TI, current monitoring systems typically fail to catch these nanosecond-level faults, which end up as unplanned outages that the company estimates cost hundreds of thousands of dollars per hour.
Nanosecond-Level Electrical Telemetry
According to TI, the ADC34DSO75 is the industry’s highest-performance 3-gigasample-per-second (GSPS) converter. It combines that high-speed sampling with on-chip digital signal processing to detect and capture transient events in real time, continuously and at low power. The company says it’s thousands of times faster than current solutions and the first to offer event-based remote telemetry, which would avoid having to debug faults on-site with oscilloscopes.
The product datasheet provides some details the announcement leaves out: it’s a four-channel, 14-bit converter in a 13.8 x 13.8 mm package. It also shows the chip is still in preproduction (preview) and lists no price. Leadership claims — such as being the first or highest-performing — come from TI and aren’t accompanied by specific comparisons.
Protection for 800V Racks and More Precise Clocks
The second announcement, the LMI800PS, is what TI calls the first isolated hot-swap controller for 800V. It lets equipment be safely inserted into a shared power bus and quickly isolates a fault so it doesn’t affect the rest of the rack. It replaces a discrete five-chip solution with a single package, integrates isolated power and PMBus telemetry, and, according to the company, cuts board space by more than 60%. It offers reinforced isolation of 5 kVrms and supports ±400V and 800V distributions, in line with the data center industry’s shift to 800V electrical architecture.
The third is the LMK6B, an oscillator based on bulk acoustic wave (BAW) technology that TI advertises with 9.6 femtoseconds of jitter at 625 MHz and high power-supply ripple rejection (PSRR). The company explains that with transmission speeds approaching 3.2 Tbps, even a minimal variation in the clock signal can raise the error rate and destabilize the system.
| Chip | Function | Key spec per TI |
|---|---|---|
| ADC34DSO75 | Power-line telemetry | 3 GSPS, 4 channels, 14-bit |
| LMI800PS | Isolated hot-swap controller | 800V, replaces 5 chips, over 60% less board space |
| LMK6B | BAW oscillator | 9.6 fs jitter at 625 MHz |
Karthik Vasanth, vice president and general manager of TI’s Data, Converters and Clocks business unit, argues that the scale of AI makes real-time visibility and architectural stability more necessary than ever. TI rounds out its OCP presence with an October 15 talk by David Reusch, a power electronics engineer, on designing DC/DC converters for 800V data centers.
Frequently Asked Questions
What is the TI ADC34DSO75?
It’s a 3 GSPS, four-channel, 14-bit analog-to-digital converter designed to continuously monitor data center power lines and catch nanosecond-level faults.
What is the LMI800PS for?
It’s an isolated hot-swap controller for 800V and ±400V distributions that protects a rack’s shared power bus when equipment is connected or a load fails.
Are these chips available yet?
