The AMC1203PSA is a precision, galvanically isolated delta-sigma modulator from Texas Instruments designed for current sensing applications. It provides 16-bit resolution with a 40 ksps sampling rate and an internal 10 MHz clock.
Key electrical specs: It operates with a ±250 mV peak-to-peak input voltage range and a linear input range of ±280 mV. The device features a typical SNR of 85 dB and SFDR of 95 dB. It has a common-mode transient immunity (CMTI) of 15 kV/µs minimum. Power consumption is typically 80 mW. The high-side and low-side supply voltages range from 4.5V to 5.5V.
Isolation and package: The AMC1203PSA provides basic isolation with a withstand isolation voltage of 4000 Vrms, working isolation of 560 Vrms, and transient isolation of 4 kVpk. It has a creepage and clearance of 8 mm minimum. The device is available in an 8-pin SOP (PSA) package with surface mount mounting. Operating temperature range is -40°C to +105°C.
Design context: This modulator is suitable for precision current sensing in motor control, power inverters, and other industrial applications requiring galvanic isolation. The SPI interface allows easy connection to microcontrollers or DSPs. The internal clock simplifies design.
