Part Description
The LM4132 family of precision voltage references performs comparable to the best laser-trimmed bipolar references, but in cost-effective CMOS technology. The key to this breakthrough is the use of EEPROM registers for correction of curvature, temperature coefficient (tempco), and accuracy on a CMOS band-gap architecture allowing package-level programming to overcome assembly shift. The shifts in voltage accuracy and tempco during assembly of die into plastic packages limit the accuracy of references trimmed with laser techniques. Unlike other LDO references, the LM4132 can deliver up to 20 mA and does not require an output capacitor or buffer amplifier. These advantages along with the SOT-23 packaging are important for space-critical applications. Series references provide lower power consumption than shunt references, because they do not have to idle the maximum possible load current under no-load conditions. This advantage, the low quiescent current (60 µA), and the low dropout voltage (400 mV) make the LM4132 ideal for battery-powered solutions. The LM4132 is available in five grades (A, B, C, D and E) for greater flexibility. The best grade devices (A) have an initial accuracy of 0.05% with a specified temperature coefficient of 10 ppm/°C or less, while the lowest grade devices (E) have an initial accuracy of 0.5% and a tempco of 30 ppm/°C.
