It delivers a stable 2.5V output with a tolerance of ±0.2% and a temperature coefficient of 40ppm/°C, making it a solid choice for precision analog circuits that need a low-drift reference without a dedicated supply rail. As a shunt reference, it behaves like a precision Zener diode — you bias it through a resistor from a higher supply voltage, and it sinks enough current (up to 15 mA) to regulate the output. The minimum cathode current is only 50 µA, so it works in low-power designs too. The SC-70 footprint is hand-solderable with a fine tip, and there's a healthy maker community around it for breadboard-friendly breakouts. ## Package and mounting Low-frequency noise from 0.1 Hz to 10 Hz is specified at 18 µVp-p. That's the flicker noise you'd see as wander on a scope trace — for a 2.5V reference, it's about 7 ppm of the output, which is fine for 12-bit ADC references but may need averaging for 16-bit systems. The 40ppm/°C temperature coefficient means the output shifts by roughly 100 µV over a 25°C swing. If your board sees a 60°C delta (e.g., from cold start to full load), budget about 6 mV of drift — acceptable for most industrial control loops, but check your ADC's LSB size. ## Active production — sourcing and compliance It ships in Tape & Reel (TR) or Cut Tape (CT) options, both surface-mount ready. The SC-70-3 package is widely stocked; lead times are typical for a mature Analog Devices shunt reference — confirm availability at quote time against your BOM quantity.","metaTitle":"ADR525BKSZ-REEL7 Analog Devices 2.5V Shunt Reference ±0.2%","metaDescription":"Analog Devices ADR525BKSZ-REEL7 shunt voltage reference: fixed 2.5V output, ±0.2% tolerance, 40ppm/°C tempco, SC-70 package.
