7 / 13 page 50ppm/°C Precision Micropower Shunt Voltage References with Multiple Reverse Breakdown Voltages _______________________________________________________________________________________ 7 Note 1: All devices are 100% production tested at +25°C and are guaranteed by design for TA = TMIN to TMAX, as specified. Note 2: The limit over the full temperature range for the reverse breakdown voltage tolerance is defined as: [VRTOL] ±[( ΔVR / ΔT) X (maxΔT) X (VR)] where ΔVR / ΔT is the VR temperature coefficient, maxΔT is the difference from the +25°C reference point to TMIN or TMAX, and VR is the reverse breakdown voltage. The total tolerance over the full temperature range for the different grades where max ΔT = +100°C is shown below: • A grade: ±0.6% = ±0.1% ±50ppm/°C ✕ 100°C • B grade: ±0.7% = ±0.2% ±50ppm/°C ✕ 100°C • C grade: ±1.0% = ±0.5% ±50ppm/°C ✕ 100°C Note 3: Guaranteed by design.
