Small-footprint voltage reference helps portable and battery-powered applications

The REF34xx device, from Texas Instruments, is a low-temperature drift (6ppm/C), low-power, high-precision CMOS voltage reference, offering ±0.05% initial accuracy, low operating current with power consumption of less than 95µA. This device also provides very low output noise of 3.8µVp-p/V, which give its ability to manage high signal integrity with high-resolution data converters in noise critical systems. With a small SOT-23 package, the device provides enhanced specifications and pin-to-pin replacement for MAX607x and ADR34xx. The device family is compatible with most of the ADC and DAC such as ADS1287, ADUCM360, ADS1112. Stability and system reliability are additionally improved by the low output-voltage hysteresis of the product and low long-term output voltage drift. Moreover, the small size and low operating current of the devices (95µA) can help portable and battery-powered applications. The device is specified for the wide temperature range of -40C to +125C.
