REF2033AIDDCR TI Voltage Reference
The REF2033 is a precision series voltage reference providing two outputs: a fixed 3.3-V (primary) and a 1.65-V (secondary) output that tracks the primary. It operates from a 3.35-V to 5.5-V input, drawing only 120 µA typical supply current, with an initial accuracy of ±0.05% and a temperature coefficient of 8 ppm/°C (max). Packaged in a 5-pin SOT-23 (DDC), it is ideal for powering dual-supply ADCs, DACs, and precision signal chains requiring two closely matched reference voltages. Applications include portable medical devices, test and measurement equipment, and industrial automation. In stock at HL Electronics – request a quote for fast delivery.
