Hi,
Can I parallel 4x opamps 1 master 3 slaves in cascade each one another ? So I can drive 600ohms resistor in feedback of my shelf filter audio circuit with 22nF high grade duelund capacitor (no smaller value existing) and get the right RC value for…

車用系統的相關標準與規格要求十分繁雜，涵蓋電磁干擾（EMI）、散熱性能、功能安全等指標，不過最能直接影響消費者滿意度的問題莫過於「可聽見雜訊」。接下來，我將分析可聽見雜訊的常見來源，並說明如何利用搭載 TI 雙隨機展頻技術（DRSS）的元件，幫助您消除設計中的雜訊。
DRSS 技術簡介
這一切要從 EMI 談起，汽車 EMI 標準非常嚴格，對於降壓穩壓器這類無電池開關電源尤其如此…
My original design for parallel op amps was published in1984 in a Burr-Brown data sheet for the OPA111, a then- new dielectrically- isolated op amp. It is shown as Figure 16, 'An N-Stage Parallel-Input Amplifier for Reduced Relative Amplifier Noise at…

I've been in the hi end audio design business for most of my life. This is a solution to something that ain't broke.
A good quality audio pot worked beautifully for many years and still does. No one complains about the lack of a perfect log response…
