The OPAx197 family (OPA197, OPA2197, and OPA4197) is a new generation of 36-V operational amplifiers.

These devices offer outstanding dc precision and ac performance, including rail-to-rail input/output, low offset (±25 µV, typical), low offset drift (±0.25 µV/°C, typ), and 10-MHz bandwidth.

Unique features such as differential input-voltage range to the supply rail, high output current (±65 mA), high capacitive load drive of up to 1 nF, and high slew rate (20 V/µs) make the OPA197 a robust, high-performance operational amplifier for high-voltage, industrial applications.

The OPA197 family of op amps is available in standard packages and is specified from –40°C to +125°C.

TIDA-01555 — 彈性介面 (PRU-ICSS) 參考設計,適用於使用多個 ADC 的同步、同調的 DAQ

此參考設計展示了連接多個高電壓雙極輸入、8 通道、多工輸入 SAR ADC (6) 與 Sitara Arm 處理器的介面實作,以使用程式化即時單元 (PRU-ICSS) 擴充輸入通道數量。ADC 配置為在所有 ADC 中同時取樣相同通道。此設計透過每個線路週期取樣 640 個樣本,強調 PRU-ICSS 處理 1536ksps (每個取樣 = 16 位元) 資料率的能力。在 50Hz 週期中,同步對應 6 個 ADC 中每通道 32ksps (每週期 640 個取樣*50Hz*6 個 ADC*8 通道 = 1536 ksps)。此外,第二個 PRU 用於對資料進行後處理,以實現一致的取樣。
