Texas Instruments AMC0x30S/AMC0x30S-Q1 Precision Isolated Amplifiers

Texas Instruments AMC0x30S/AMC0x30S-Q1 Precision Isolated Amplifiers have a ±1V, high impedance input and fixed-gain, 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. It is highly resistant to magnetic interference and is certified to provide basic isolation up to 3kVRMS (D package) (60s) and reinforced isolation up to 5kVRMS (DWV package).

The AMC0x30S/AMC0x30S-Q1 outputs a single-ended signal proportional to the input voltage with a fixed gain of 1V/V. The output of the AMC0x30S is designed to connect directly to the input of an Analog-to-Digital Converter (ADC). The voltage applied to the REFIN pin sets the output voltage at 0V input. The AMC0x30S/AMC0x30S-Q1 devices come in 8-pin, wide- and narrow-body SOIC packages and are specified over the temperature range of –40°C to +125°C. The Texas Instruments AMC0x30S-Q1 devices are AEC-Q100 qualified for automotive applications.
