REF70 – Ultra-high-precision voltage reference with low noise and low drift

Texas Instruments REF70 Precision Voltage Reference is a family of high-precision series voltage references that offers the industry’s lowest noise (0.23ppm_p-p). They offer a very low-temperature drift coefficient (2ppm/°C) and high accuracy (±0.025%). The REF70 offers a high PSRR, low dropout voltage, and excellent load and line regulation to help meet strict transient requirements. This combination of precision and features is designed for applications such as test and measurement that demand a precise reference. These devices should be paired with precision, high-resolution data converters such as ADS8900B, ADS127L01, and DAC11001A, to achieve optimal performance in the signal chain. The REF70 is also designed for noise-sensitive medical applications such as ultrasound and X-ray to help enable low-noise measurements from the analog front end.
