As a professional supplier in the field of electronic components, Shenzhen Mingjiada Electronics Co., Ltd. supplies AMC1200BDUBR Precision Current Sense Isolation Amplifier in stock.
Product Overview Of AMC1200BDUBR
The AMC1200BDUBR is a fully differential isolation amplifier from Texas Instruments that uses advanced silicon-based isolation technology to achieve up to 4250 VPEAK electrical isolation through a silicon dioxide (SiO2) isolation barrier. The AMC1200BDUBR device in a SOP-8 package (9.55mm × 6.67mm × 3.35mm), the operating temperature range as wide as -40 ℃ to 105 ℃, suitable for a variety of harsh industrial environments.
The AMC1200BDUBR has a built-in differential input range of ±250mV, which is particularly suitable for use with shunt resistors to achieve high-precision current detection.The AMC1200BDUBR has a fixed gain of 8V/V, with a gain error of only ±0.5% over the full temperature range, ensuring measurement accuracy. Notably, the AMC1200BDUBR has a common-mode transient immunity of 10kV/µs, which effectively suppresses the impact of switching noise on the measurement system.
Core Features Of AMC1200BDUBR
Highly Accurate Current Detection
Optimised for current sensing applications, the AMC1200BDUBR's input stage is specially optimised for low-voltage signals from shunt resistors.The AMC1200BDUBR has an extremely low input distortion voltage (200µV) and excellent temperature drift characteristics to maintain stable measurement accuracy over the full operating temperature range. 100kHz, enabling accurate capture of rapidly changing current signals.
Superior Isolation
The AMC1200BDUBR uses Texas Instruments' patented capacitive isolation technology, which is UL1577 and VDE V 0884-10 certified, with isolation withstand voltages up to 3kVrms (1 minute duration) or 4250VPEAK. The AMC1200BDUBR's isolation barrier has a very high level of immunity to magnetic disturbances, which ensures stable operation in environments of strong EMI, such as motor drives. The output common-mode voltage of the AMC1200BDUBR can be automatically adjusted to 3V or 5V low-side supply, simplifying system design.
Low Power Consumption and Wide Voltage Operation
The AMC1200BDUBR operates over a wide voltage range of 2.7V to 5.5V, with a supply current of only 5.4mA and a maximum power consumption of 82.5mW, making it ideal for battery-powered or low-power applications.The AMC1200BDUBR has a common-mode rejection ratio (CMRR) of up to 95dB, effectively suppressing common-mode noise and improving the signal-to-noise ratio of the system.
