The ratiometric matching of the RES11A-Q1 provides a benefit not just for initial conditions, but also when considering parametric drift. The resistors must be considered individually, in absolute terms, and ratiometrically to each other, in matched terms. The absolute temperature coefficients of each resistor show strong correlation, with the coefficient of R_IN1 comparable to that of R_IN2 and the coefficient of R_G1 comparable to that of R_G2. The absolute temperature coefficient (in Ω/°C) of each R_G is approximately G_nom times greater than that of the comparable R_IN; hence, the normalized absolute temperature coefficient (in ppm/°C) of every resistor is about the same.

Because the resistors of the RES11A-Q1 are interdigitated, and occupy a small footprint, the die temperature of the device is effectively common to each of the four resistors. As the temperature changes, each resistor experiences a similar temperature rise. Because the resistors have very similar temperature coefficients, the ratio of R_G to R_IN is well preserved. For example, the RES11A40-Q1 has a typical absolute temperature coefficient of approximately 18 ppm/°C for R_IN or R_G. When considered in ratiometric terms, the typical temperature coefficient of t_D1 or t_D2 is –0.2 ppm/°C, and the temperature coefficient of t_M is 0.05 ppm/°C.
