6-lead SOT-23

The ADR3412 / ADR3420 / ADR3425 / ADR3430 / ADR3433 / ADR3440 / ADR3450 are low-cost, low-power, high precision voltage references, featuring ± 0.1% initial accuracy, low operating current and low output noise in a small SOT23 package. For high accuracy, output voltage and temperature coefficient are trimmed digitally during final assembly using Analog Devices’ proprietary Digi-Trim^® technology.

Stability and reliability are further improved by the devices’ low output voltage hysteresis and low long-term output voltage drift.

Furthermore, the low operating current of the device (100 μA max) facilitates usage in low-power devices, while its low output noise helps maintain signal integrity in critical signal processing systems.

These CMOS are available in a wide range of output voltages, all of which are specified over the industrial temperature range of −40°C to +125 °C.

Tools & Simulations

Signal Chain Designer

Signal Chain Designer is a web-based tool designed to create and simulate complex precision signal chains. See your circuit’s performance before you commit to your PCB: transfer function, noise, power consumption, input range, and DC error. Quickly experiment with different parts and architectures. Signal chains can be exported to LTspice for further analysis.
