GENERAL DESCRIPTION

Table 2. Voltage Reference Choices from Analog Devices

The ADR3412/ADR3420/ADR3425/ADR3430/ADR3433/

ADR3440/ADR3450 are low cost, low power, high precision

CMOS voltage references, featuring 0ꢀ1ꢁ initial accuracy, low

operating current, and low output noise in a small SOT-23

packageꢀ For high accuracy, output voltage and temperature

coefficient are trimmed digitally during final assembly using

Analog Devices, Incꢀ, patented DigiTrim® technologyꢀ

Stability and system reliability are further improved by the low

output voltage hysteresis of the device and low long-term output

voltage driftꢀ Furthermore, the low operating current of the

device (100 μA maximum) facilitates usage in low power

devices, and its low output noise helps maintain signal integrity

in critical signal processing systemsꢀ
