ADR3412ARJZ-R7

ADR3412/ADR3420/ADR3425/ADR3430/ADR3433/ADR3440/ADR3450 are low cost, low power, high precision CMOS voltage references featuring ±0.1% initial accuracy, low operating current, and low output noise, housed in a compact SOT-23 package. To achieve high precision, the output voltage and temperature coefficient are digitally trimmed during final assembly. Low output voltage temperature hysteresis and low long-term output voltage drift further enhance the stability and system reliability of these devices. In addition, the low operating current (100 μA maximum) makes these devices suitable for low power applications, while the low output noise helps maintain signal integrity in critical signal processing systems. These CMOS voltage references offer a wide output voltage range, and all devices are rated for the -40°C to +125°C extended industrial temperature range.
