ADR3430
PRODUCTIONMicro-Power, High-Accuracy 3.0V Voltage Reference
Part Details
- Initial accuracy: ± 0.1%
- Max. temp. coefficient: 8 ppm/°C
- Operating temperature: −40°C – +125 °C
- Output current: +10 mA source/−3 mA sink
- Low quiescent current: 100 μA (max)
- Low dropout voltage: 250 mV @ 2 mA
- Output noise (0.1 – 10 Hz): <10 μV p-p at 1.2 V (typical)
- 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.
