Texas Instruments REF34xx-EP Voltage References

Texas Instruments REF34xx-EP Voltage References feature a low-temperature drift (10ppm/°C), ±0.05% initial accuracy, and a low operating current with power consumption of less than 95µA. The low-power, high-precision devices also offer a very low output noise of 3.8µVp-p/V, which allows the ability to maintain high signal integrity with high-resolution data converters in noise-critical systems. The Texas Instruments REF34xx-EP series provides enhanced specifications and pin-to-pin replacement for the MAX607x and ADR34xx in a small SOT-23 package. The small size and low operating current of 95µA make the devices ideal for portable and battery-powered applications. The low output-voltage hysteresis of the REF34xx-EP and low long-term output voltage drift further improve system reliability and stability. The REF34xx-EP is specified for the wide temperature range of –55°C to +125°C and is compatible with most ADC and DAC.
