Overview
a FEATURES Improved, Lower Cost, Replacements for Standard 1403, 1403A 3-Terminal Device: Voltage In/Voltage Out Laser Trimmed to High Accuracy: 2.
500 V ؎ 10 mV (AD1403A) Excellent Temperature Stability: 25 ppm/؇ C (AD1403A) Low Quiescent Current: 1.
5 mA max 10 mA Current Output Capability Low Cost Convenient Mini-DIP Package Low Cost, Precision 2.
5 V IC References AD1403/AD1403A* FUNCTIONAL BLOCK DIAGRAM PRODUCT DESCRIPTION PRODUCT HIGHLIGHTS The AD1403 and AD1403A are improved three-terminal, low cost, temperature compensated, bandgap voltage references that provide a fixed 2.
5 V output voltage for inputs between 4.
5 V and 40 V.
A unique combination of advanced circuit design and laser-wafer-trimmed thin-film resistors provides the AD1403/ AD1403A with an initial tolerance of ± 10 mV and a temperature stability of better than 25 ppm/°C.
In addition, the low quiescent current drain of 1.
5 mA (max) offers a clear advantage over classical Zener techniques.
The AD1403 or AD1403A is recommended as a stable reference for all 8-, 10- and 12-bit D-to-A converters that require an external reference.
In addition, the wide input range of the AD1403/AD1403A allows operation with 5 volt logic supplies, making these devices ideal for digital panel meter applications and when only a single logic supply is available.
The AD1403 and AD1403A are specified for operation over the 0°C to +70°C temperature range.
The AD580 series of 2.
5 volt precision IC references is recommended for applications where operation over the –55°C to +125°C range is required.
1.
The AD1403A offers improved initial tolerance over the industry-standard 1403A: ± 10 mV versus ± 25 mV at a lower cost.
2.
The three-terminal voltage in/voltage out operation of the AD1403/AD1403A provides a regulated output voltage without any external components.
3.
The AD1403/AD1403A provides a stable 2.
5 V output voltage for input voltages between 4.
5 V and 40 V making these devices ideal for systems that contain a single ...
