AMC0311S中文资料Precision 2V-input reinforced isolated amplifier with fixed gain, single-ended output数据手册TI规格书

描述 Description

The AMC0x11S is a precision, galvanically isolated amplifier with a 2.25V, high impedance input, fixed-gain, and single-ended output. The high-impedance input is optimized for connection to a high-impedance resistive divider or other voltage signal source with high output resistance.

The isolation barrier separates parts of the system that operate on different common-mode voltage levels. The isolation barrier is highly resistant to magnetic interference. This barrier is certified to provide reinforced isolation up to 5kVRMS (DWV package) and basic isolation up to 3kVRMS (D package) (60s).

The AMC0x11S outputs a single-ended signal proportional to the input voltage with a fixed gain of 1V/V. The output is designed to connect directly to the input of an ADC. The voltage applied to the REFIN pin sets the output voltage at 0V input.

The AMC0x11S devices come in 8-pin, wide- and narrow-body SOIC packages, and are fully specified over the temperature range from –40°C to +105°C.
