Negotiate through 1/f noise challenges towards sample sizes into the 100s of years

July 13, 2021 By Bonnie Baker Leave a Comment

Negotiate through 1/f noise challenges

Measuring and determining 1/f voltage noise over a multiple-year sample requires an operational amplifier and effective 1/f knowledge. This article shows how to identify and determine the actual op amp 1/f voltage noise across a sample size of years and explains why the 1/f voltage noise is a non-issue at higher frequencies. After many years […]

Dual 5-V op amp sports 50-MHz gain-bandwidth, low input offset voltage, 6.5 nV/√Hz input voltage noise

December 8, 2020 By Redding Traiger

STMicroelectronics’ TSV792 dual 5V operational amplifier (op-amp) combines 50MHz gain-bandwidth with precision attributes including low input offset voltage and extremely low input voltage noise of just 6.5nV/√Hz. The typical 50MHz gain-bandwidth product enables accurate amplification of high-frequency signals. Adding a fast slew rate of 30V/µs, the TSV792 is suited to photodiode-signal conditioning in battery-powered smoke detectors. […]
