LM4040
Improved Precision Micropower Shunt Voltage
Reference with Multiple Reverse Breakdown Voltages

Maxim Integrated
Note 1: All devices are 100% production tested at TA = +25°C and are guaranteed by design for TA = TMIN to TMAX, as specified.
Note 2: The overtemperature limit for Reverse Breakdown Voltage Tolerance is defined as the room-temperature Reverse
Breakdown Voltage Tolerance ±[(
VR/T)(maxT)(VR)], where VR/T is the VR temperature coefficient, maxT is the maxi-
mum difference in temperature from the reference point of +25°C to TMIN or TMAX, and VR is the reverse breakdown volt-
age. The total overtemperature tolerance for the different grades in the temperature range where max
T = +65°C is shown
below:
A grade: ±0.75% = ±0.1% ±100ppm/°C 65°C
B grade: ±0.85% = ±0.2% ±100ppm/°C 65°C
C grade: ±1.15% = ±0.5% ±100ppm/°C 65°C
D grade: ±1.98% = ±1.0% ±150ppm/°C 65°C
The total over-temperature tolerance for the different grades in the extended temperature range where max
T = +100°C is
shown below:
A grade: ±1.1% = ±0.1% ±100ppm/°C 100°C
B grade: ±1.2% = ±0.2% ±100ppm/°C 100°C
C grade: ±1.5% = ±0.5% ±100ppm/°C 100°C
D grade: ±2.5% = ±1.0% ±150ppm/°C 100°C
Therefore, as an example, the A-grade LM4040-2.5 has an over-temperature reverse breakdown voltage tolerance of ±2.5V
0.75% = ±19mV.
Note 3: Guaranteed by design.
