The XTR100, XTR102, and XTR120 (XTR1xx) family is a family of precision amplifiers with integrated highly-matched scaling resistors, making the devices an excellent choice to implement a precision 2-wire 4-to-20mA transmitter driver. The amplifier is optimized for low-power high precision applications, with zero-drift technology resulting in unparalleled offset voltage, and offset drift. With an ultra-low 40µA of typical quiescent current, the XTR1xx achieves 1.0MHz of bandwidth, a broadband noise of 40nV/√Hz, and integrated 1/f noise of 1µVPP. XTR1xx operates with supply voltages down to 1.7V, enabling low-voltage applications. XTR1xx integrates a highly-matched dual resistor of 40kΩ and 10kΩ, creating an ultra-precise ratio of 4:1 with 0.02% maximum tolerance, and ±2ppm/°C drift. XTR100 comes in a 6-pin DBV package compatible with common 5-pin SOT-23. XTR102 adds an extra input for HART signal. XTR120 is a super-set of XTR102 with a second zero-drift precision amplifier that can be used to actively filter PWM signals.
