The TLV34xx devices are single and dual CMOS operational amplifiers, respectively, with low-voltage, low-power, and rail-to-rail output swing capabilities. The PMOS input stage offers an ultra-low input bias current of 1pA (typical) and an offset voltage of 0.3mV (typical). For applications requiring excellent dc precision, the A grade (TLV34xA) has a low offset voltage of 1.25mV (maximum) at 25°C.

These single-supply amplifiers are designed specifically for ultra-low-voltage (1.5V to 5V) operation, with a common-mode input voltage range that typically extends from –0.2V to 0.5V from the positive supply rail.

The TLV341 (single) and TLV342 (dual) in the RUG package also offer a shutdown (SHDN) pin that can be used to disable the device. In shutdown mode, the supply current is reduced to 45pA (typical). Offered in both the SOT-23 and smaller SC70 packages, the TLV341 is an excellent choice for the most space-constrained applications. The dual TLV342 is offered in the standard SOIC, VSSOP, and X2QFN packages.

An extended industrial temperature range from –40°C to 125°C makes the TLV34xx flexible for use in a wide variety of commercial and industrial applications.

TIDA-00649 — 4mA 至 20mA 迴路能源採集器參考設計

TIDA-00649 參考設計展示 4mA 至 20mA 迴路供電系統的能源採集。此設計可輕鬆整合至現有安裝中，透過迴路汲取能源並產生穩定的輸出電壓。此外，電路也提供代表實際迴路電流值的類比輸出。插入損耗可降至 400mV，也可提升至最高 2.85V，以因應更高的輸出功率位準。所有這些功能都能輕鬆地為無線變壓器（WirelessHART®、Bluetooth® 低功耗 (BLE) 等）、指示燈、顯示器、人機介面 (HMI) 等裝置供電，可將現有的 4mA 無縫升級至 20mA 迴路供電系統。
