Texas Instruments AMC0x06M25/-Q1 Isolated Delta-Sigma Modulators
Texas Instruments AMC0x06M25/-Q1 Isolated Delta-Sigma Modulators are precision devices with a ±250mV differential input and digital output. The input is optimized for connection to low-impedance shunt resistors commonly utilized for current-sensing applications. The isolation barrier separates parts of the system that function on different common-mode voltage levels. The isolation barrier is highly resistant to magnetic interference. The barrier is certified to supply reinforced isolation up to 5kVRMS (DWV package) and basic isolation up to 3kVRMS (D package) (60s). The TI AMC0x06M25/-Q1 Isolated Delta-Sigma Modulators output bitstream is synchronized to an external clock. The AMC0x06M25/-Q1 combines a sinc3 and OSR 256 filter, allowing 16 effective bits of resolution or 88dB of dynamic range, at a 78kSPS sample rate.
The AMC0x06M25-Q1 is available in 8-pin, wide- and narrow-body SOIC packages. The device is fully specified over a -40°C to +125°C temperature range.
The AMC0x06M25-Q1 devices are AEC-Q100 qualified for automotive applications.
