MAX6078A/MAX6078B Low-Power, Low-Drift, Low-Noise Voltage Reference General Description Benefits and Features The MAX6078 precision voltage reference family provides 0.04% Initial Accuracy low drift and low noise at a maximum power supply current 10ppm/C (max) Temperature Drift of only 15A. Low-frequency noise is less than 12V 12V Noise (0.1Hz to 10Hz) at 2.5V P-P P-P (2.5V output voltage option) and the temperature coeffi- 15A Supply Current cient of the output voltage is less than 10ppm/C. Long-Term Drift: 16ppm (typ, 4000hrs) 3mA Source/Sink Load Current The reference output can sink and source up to 3mA of Filter Option Reduces High-Frequency Noise load current and the top grade provides an initial accu- 100mV Dropout Voltage racy of 0.04%. The low-drift and low-noise specifications 1.5mm x 1.3mm (0.5mm pitch), 6-Bump WLP and enable enhanced system accuracy, making these devices 2mm x 3mm, 8-Pin TDFN-EP Packages ideal for high-precision industrial applications. A noise re- Voltage Output Options: 1.25V, 2.048V, 2.5V, 3.0V, duction (NR) input pin allows connection of an external ca- 3.3V, 4.096V, and 5.0V pacitor to reduce wideband noise. Available output volt- ages include 1.25V, 2.048V, 2.5V, 3.0V, 3.3V, 4.096V, Ordering Information appears at end of data sheet. and 5.0V. The tiny, 6-bump WLP and small, 8-pin TDFN-EP pack- ages are suitable for systems where circuit board area is limited. The operating input voltage can range from 2.3V to 5.5V. Operation is specified over the extended industri- al temperature range of -55C to +125C.
